Knowing if your cat has allergies is not always easy. Allergic cats with itchy skin will often spend more time grooming than actually scratching so signs of allergies are easy to miss. If your cat is scratching or over grooming, they might be having an allergic reaction to something around them or their immune system could be reacting to something they are eating.
Cat allergies can be caused by many of the same things that affect us including mould, mildew, dust mites, insect bites, pollen, toxic plants and certain proteins found in food. Flea bites can also cause allergic reactions in cats so keeping your cat’s flea treatments up to date can be important.
Common signs of allergies include any or all of the following:
- Skin rash
- Hair loss
- Ear redness
- Scaly skin
- Feline acne
- Red lesions on the upper lip (usually due to over grooming)
- Vomiting or diarrhoea
- Ear infections (sometimes foul-smelling, crusty or leaking pus)
If you notice any of these signs in your pet, make an appointment to see your vet straight away. Sometimes the solution can be as simple as changing your cat’s diet, or more complex treatments such as medications or shampoos may be required.
