Yes, Cats Can Have Allergies Too

Most people think about allergies as something humans deal with. Sneezing, itchy eyes, maybe a reaction to pets or pollen. But cats can have allergies too, and they often show up in ways that are easy to miss.

If your cat has been scratching more than usual, over-grooming, or just not acting like themselves, it may be time to consider that your kitty may have developed some allergies. The below info will help you spot potential allergies, but remember if you suspect there may be any health issue with your cat, your first call should be to your trusted veterinarian.

Causes of Allergies in Cats — Environmental allergies (pollen, dust, mold, household cleaning products); flea allergies (one of the most common and overlooked causes — some cats are extremely sensitive to flea saliva); food allergies (certain proteins, often chicken, beef, or fish). According to the ASPCA and Cornell Feline Health Center, allergies can develop at any point in a cat's life, even if they've never had issues before.

Allergy Symptoms in Cats — Cats hide discomfort, so signs look different than in humans: frequent scratching (especially around the head and neck), over-grooming or bald patches, red/irritated skin or sores, ear infections or head shaking, vomiting or digestive issues in some cases. Symptoms often overlap with other issues, so it usually takes a process of elimination, and sometimes help from a vet, to figure out the exact cause.

How Allergies Are Usually Managed — Depending on the trigger, a vet might suggest consistent flea prevention (even for indoor cats), a limited-ingredient or prescription diet, reducing environmental triggers at home, or medications to control itching or inflammation. The VCA Animal Hospitals emphasizes that management is usually about reducing exposure and keeping your cat comfortable, rather than completely eliminating the allergy.
