If your cat is losing hair, it could be down to any of a number of reasons. Ringworm, fungal skin infections, hormonal problems, infestations of fleas or mites, allergies or psychological causes can all be the cause of the problem.

Hair loss can also be down to something as simple as grooming. Cats keep clean by licking themselves - but not every cat is an expert, particularly overweight cats! Others, meanwhile, may groom too much. Excessive grooming can be spotted when a cat starts to lose hair, especially on the belly, the back and inside the back legs.

Excessive hair loss can also occur after kittening, in old age, and when cats are ill or fed a poor diet.

Treatment
If you notice that your cat has started losing hair, your first stop should always be with the vet for a thorough physical examination. This may involve taking skin scrapings, blood tests and hair samples for testing.

Initially, your vet will look for parasitic infestations, and discuss your flea treatment regime. If this is effective and up to date, your vet will need to investigate further.

Behavioural reasons for your cat's hair loss are best backed up by evidence. So if you suspect your cat is stressed and anxious, keep a diary of times and specific circumstances when hair licking and pulling takes place. Your vet will then be able to assess whether you simply need to change something in your cat's environment, or whether a prescription of anti-anxiety medication is needed for your pet.
