If your cat is still having an allergic reaction after this treatment, your vet may try to rule out any food allergies by placing them on an exclusion diet. This lasts for around eight weeks, during which time if your cat's symptoms disappear, the vet will then give your cat their original food; if the symptoms reappear, they'll conclude it's sensitive to an element of this diet.
If the exclusion diet process is unsuccessful, it's likely your cat is suffering from an allergy that requires prescription medication.
The impact of diet on your cat's allergy
Your cat's diet directly affects their skin, the largest organ in their body. A food designed specifically for cats with hypersensitive skin can help limit any adverse reactions to food and support them in developing good skin health.
These foods have specially chosen protein and carbohydrates that are less likely to cause an allergic reaction in your cat; ones that are highly digestible and may not be commonly used in most manufactured food. The food may also include omega 3 long chain fatty acids, which help manage any skin reactions (such as inflammation) and biotin, niacin and pantothenic acids—these help prevent your cat's skin drying out and strengthens its ability to protect them against irritants.
If you notice any of the symptoms of an allergic reaction in your cat, make sure to visit your local vet. Together, you'll be able to work out how to support your cat's health and improve the quality of their fur and skin.
