Rodents such as hamsters and degus have natural instincts that drive them to run and explore their surroundings. In the wild their lives revolve around activity, foraging for food and evading predators. An exercise wheel is an excellent way for them to satisfy these innate needs. Running in a wheel lets rodents act on their hunting instincts and get the physical exercise that is essential to their health and wellbeing. The activity a wheel provides helps them maintain a healthy body weight, improves the condition of the heart and circulation, and aids digestion. Running in a wheel can also work as a form of mental stimulation, since it requires the animal to concentrate and think creatively, which matters for its overall wellbeing. In this way the wheel becomes not merely a source of movement but a means of giving rodents a healthy, active life.

Why the wrong wheel can cause health problems

If a wheel is too small, rodents are forced to run in an awkward, unnatural posture, which can injure the spine and strain the joints. Too little running space also limits their natural range of movement, making the exercise less comfortable and less effective.

What is more, wheels with rigid or hard running surfaces can chafe and irritate the feet, and in some cases even cause injury. Rodents can also hurt themselves if the wheel lacks proper safeguards, such as mesh or side guards that stop them slipping into gaps. The noise made by a poor-quality wheel whose parts rub together can cause stress and anxiety, disrupting the animal’s natural rhythm of sleep and activity. A badly chosen wheel fails to provide enough physical and mental stimulation, which can lead to obesity, low mood and behavioural problems such as excessive aggression or nervousness. That is why it is important to choose a wheel carefully, to suit your rodent’s needs and protect its health and wellbeing.

Types of exercise wheel available

1. Classic wheels: the most common type, consisting of a rotating disc mounted on a base. They may be made of plastic or metal and come in various sizes, so you can pick one to suit a particular species of rodent.
2. Mesh wheels: these models have a mesh running surface, which gives a rodent’s feet better grip and reduces the risk of slipping. That makes them safer, and their design allows for a more natural running action.
3. Enclosed wheels: more advanced models that are closed at the sides so rodents cannot fall out. They are particularly recommended for small or slightly clumsier animals.
4. Wheels with bearings: good-quality wheels often come fitted with bearings, which make them run more quietly and smoothly. An excellent choice for owners whose rodents run at night, as it keeps the noise down.
5. Adjustable wheels: some models allow the height or position to be adjusted, so the wheel can grow with the animal. A practical solution that extends the wheel’s useful life.
6. Tilting wheels: these are designed to swing from side to side, which stimulates the rodent’s natural movement and makes running more appealing.
7. Wheels with extra features: some wheels offer additional features such as built-in toys, tunnels or treat compartments, which make running more interesting still.

How to choose the right wheel for your rodent

• Wheel size: getting the size right is the single most important factor. The wheel should be large enough for the rodent to run in a natural, comfortable position without arching its back. For hamsters a diameter of 25–30 cm is usually recommended, while larger rodents such as degus do better with bigger models still.

• Species of rodent: different species have different needs. Hamsters, for instance, may prefer classic or enclosed wheels, while guinea pigs do better with larger, more stable models. It is important to match your choice to the specific requirements of the species.

• Running surface: pay attention to the surface of the wheel. Models with mesh or a non-slip covering offer better grip and greater safety, reducing the risk of slips and injuries, as rodents are then more inclined to run naturally.

• Stability and construction: when choosing a wheel, it is worth considering how stable it is. The wheel should be solidly built and firmly mounted so that it does not tip over during use. Models with a base are usually more stable.

• Type of wheel: choosing between an enclosed, classic or adjustable wheel can make a difference to your rodent’s comfort. Enclosed models are safer, as they prevent the animal from falling out, while adjustable ones can be altered to suit a growing pet.

• Quiet running: for a peaceful home, choose a wheel with bearings, which runs more quietly. This matters especially when your rodent runs at night, as it keeps the noise to a minimum.

How to tell that the wheel is the wrong one

Spotting that a wheel does not suit your rodent takes some observation of its behaviour and condition. First of all, if the animal seems to avoid using the wheel, that may be a sign it does not feel comfortable in it. Signs such as reluctance to run, placing the feet awkwardly or jumping straight back out may point to the wrong size of wheel. What is more, if the rodent appears to struggle with its balance or its running looks uneven, the wheel is probably too small or unstable. It is also worth checking the animal’s feet for chafing or sores, which suggest the running surface is too hard. Sometimes the noise a wheel makes in use also indicates poor build quality, which can leave the rodent stressed. If any of these problems appear, consider replacing the wheel with a more suitable model that will keep your rodent comfortable and safe while it plays.

What is an ear infection?

An ear infection in a cat, also known as otitis externa, involves inflammation and infection within the outer ear, which leaves the animal uncomfortable and in pain. The condition can have a variety of causes, including bacterial, fungal or parasitic infections, as well as allergies that irritate the lining of the ear. Inflammation of this kind can lead to excessive wax production, which blocks the ear canal and produces an unpleasant smell. Ear infections in cats can also stem from foreign bodies, such as bits of fluff or dirt, which irritate the delicate tissues further. Left untreated, an ear infection can lead to more serious health problems, including a middle ear infection, which is why early diagnosis and treatment matter so much.

How to spot an ear infection in your cat

Recognising an ear infection in a cat comes down to observing the clinical signs. Owners should look out for the following symptoms:

• Itching: the cat may scratch its ears vigorously or rub them against various surfaces.
• Excess wax: a brown or black discharge coming from the ear can be a sign of inflammation.
• Unpleasant smell: a sharp or unpleasant odour from the ears often points to an infection.
• Pain and discomfort: the cat may show signs of pain, such as avoiding having its head touched, irritability or a change in behaviour.
• Changes in appetite: the pain of an ear infection can put a cat off its food.

What causes ear infections in cats?

Ear infections in cats have a range of causes, and several factors may act alone or together to produce inflammation. Among the most common are infections, which may be bacterial or fungal. Bacteria such as Staphylococcus and Pseudomonas thrive in the warm, damp environment of the ear, particularly where the skin inside it has been damaged. Fungi, especially Malassezia, can also cause infection, above all in cats with a weakened immune system. 

Another significant factor is parasites, including fleas and mites such as Otodectes cynotis, which cause intense itching and irritation and open the door to secondary infections. Allergies, both dietary and environmental (to pollen or dust, for example), also contribute to ear infections by inflaming the epithelial tissue of the outer ear. Anatomical differences, such as an unusually shaped ear flap or ear canal, can predispose a cat to ear problems too, since they restrict ventilation and allow wax to build up.

 On top of that, cats kept in unhygienic conditions, where cleanliness is neglected, run a greater risk of ear infections. There are behavioural factors as well: scratching the ears excessively can cause injury and introduce bacteria into the ear, which again triggers inflammation.

How to prevent ear infections in cats

Preventing ear infections in cats calls for a systematic approach and steps aimed at keeping the ears healthy and heading off potential infections. The key is to check your cat’s ears regularly so that any worrying signs, such as excess wax, an unpleasant smell or irritation, are picked up early. Owners should keep the ears clean and wash them regularly, but carefully, so as not to damage the delicate tissues, and it is best to leave the job to a veterinarian. 

Keeping the cat’s surroundings clean matters just as much, including regular cleaning of the places where it spends its time, so that allergens and micro-organisms do not accumulate. For cats prone to allergies, it is important to identify and avoid the substances that trigger a reaction, which can help prevent inflammation of the ears. 

Using flea and worming treatments is essential too, in order to limit the risk of parasites that cause irritation. Regular veterinary check-ups, moreover, allow any health problems to be caught early and prevent infections from taking hold. 

Diagnosing ear infections

Diagnosing an ear infection in a cat usually begins with a detailed history taken by the veterinarian. The owner should provide information about the symptoms, the cat’s medical history and any changes noticed in its behaviour, such as itchy ears, excess wax or an unpleasant smell. The vet then moves on to a physical examination, which involves a close look at the ears, an assessment of their appearance and an evaluation of any discharge. In many cases microbiological testing is also ordered, in which samples from the ear are analysed for bacteria, fungi or parasites. Imaging such as ultrasound is sometimes used as well, to assess the state of the inner ear in more complicated cases. Where inflammation is confirmed, the vet may prescribe appropriate treatment or refer the cat to a specialist, such as a veterinary ear specialist who deals with more complex ear conditions. Accurate diagnosis is essential if an ear infection is to be treated effectively and further complications avoided.

How are ear infections in cats treated?

If you suspect your cat has an ear infection, see a veterinarian as soon as possible. Treatment may involve:

• Medication: the vet will prescribe suitable anti-inflammatories, antibiotics and painkillers.
• Ear cleaning: in some cases the veterinarian will carry out a professional ear clean, removing excess wax and dirt.
• Topical preparations: ear drops or ointments can be an effective way of easing inflammation.

In summary

An ear infection in a cat is a serious problem, but one that can be recognised, prevented and treated successfully. Watching your cat’s behaviour closely and seeking veterinary help early can make a real difference to its comfort and keep the risk of further complications to a minimum. Keeping the ears clean, guarding against parasites and seeking medical help as soon as worrying signs appear are the key steps

What are pheromones?

Pheromones are chemical substances released by an organism that can influence the behaviour, emotions and reactions of other individuals of the same species. They work as a form of chemical communication, conveying information about territory, readiness to breed, emotional state or danger. Pheromones are picked up by the sense of smell, reaching specialised receptors in the nose, which then trigger the appropriate behavioural response. In animals such as dogs and cats, pheromones play a key role in social interaction and in forming the bond between mother and offspring. Pheromones are used in pet products to support emotional wellbeing, reduce stress and anxiety, and encourage positive behaviour.

Pheromones in feline and canine therapy

Pheromones are used more widely in cats than in dogs, because two different types have been reproduced and brought into general use for them. The first are the appeasing pheromones of the mammary area, which have a calming effect and provide a sense of safety and comfort, much as they do in dogs. The second are the facial pheromones, also known as the F3 fraction, which cats release when they rub against objects to mark the places and things where they feel content and secure. In dogs, only analogues of the appeasing pheromone produced by a nursing bitch have been used so far. These pheromones are intended to calm the dog and give it a sense of security.

Pheromone products and how they work

1. Pheromone collars: these contain synthetic pheromones. They work by releasing pheromones into the surroundings, which can reduce the anxiety and stress associated with situations such as separation or a new environment.
2. Diffusers: these release pheromones into the air, creating a calming atmosphere.  They are designed to mimic the natural pheromones cats produce, which helps ease stress and increase the animal’s sense of security.
3. Sprays: these products can be applied locally inside carriers or on bedding, releasing pheromones that calm animals in difficult situations. They act quickly, which makes them ideal for sudden bouts of stress.
4. Sprays and drops: some preparations contain pheromones in liquid form, which can be given to the animal or used in its surroundings. They work by introducing pheromones into the body, which can help reduce anxiety and stress.

How pheromones work in pet products

Pheromones are species-specific, which means dogs respond only to pheromones produced by other dogs, and cats only to feline pheromones.

Pheromones are entirely safe and cause no side effects. They can be used in young and older animals alike, and in unwell animals taking various medicines, since they do not interact with any drugs. Importantly, pheromones cannot be overdosed; the animal’s response stays the same regardless of the concentration, provided the amount of pheromone is enough to produce a response in the first place. If necessary, pheromones can be used continuously over long periods, even for months and in some cases years.

It is also worth noting that pheromones are odourless. It is perfectly normal to smell nothing at all once a pheromone product has been activated. Substances of this kind work invisibly, acting on the animal’s emotions.

The effects of pheromones vary from one animal to another. It is not entirely clear what accounts for these differences, but every animal may respond to pheromones differently, and even the same animal may respond differently at different stages of life. Be prepared, then, to try a product out and see how it works for your particular pet.

When can pheromones be used?

Pheromones in pet products can be especially useful in the many situations that leave dogs and cats stressed and anxious. During a visit to the vet, for instance, where animals often feel uneasy, a pheromone diffuser or spray can help settle them. Likewise, during a house move or when a new family member arrives, pheromones can soften the stress of a sudden change of surroundings. In situations such as thunderstorms, loud noises, fireworks or other stressful sounds, pheromone products can help animals feel safer and more comfortable. On long journeys or during transport, they can also support animals as they adjust to unfamiliar conditions, which in turn makes settling into a new place easier. Using such products in these circumstances can make a real difference to how animals feel and how they react to stressful triggers.
