Just like people, cats can develop allergies to certain ingredients in their food. This often causes skin and tummy problems.
Food allergies develop when the immune system mistakenly sees a food type as dangerous and overreacts to it. Food allergies usually develop by 4-5 years of age.
It’s not always easy finding out what your cat is allergic to but symptoms can be improved (and in some cases eliminated) if you feed your cat a diet that suits them.
