Book a vet visit

This is not usually an emergency on its own – contact your vet if it lasts, gets worse or your cat seems unwell in any other way. Fleas remain the most common cause of skin disease in cats in most countries, but they are not the only cause of itching.

What to do now

What you can do now

  1. Contact your vet.
  2. Note when it started, how often it happens and what else you see.
  3. Take a photo or short video to show the vet.
  4. Keep fresh water available.
  5. Let your cat rest somewhere calm.

Don't

  • Do not give any human medicine.
  • Do not wait if it gets worse.
