What it is

Rabies is a deadly virus that can spread between animals and people.[1] It travels through saliva, so cats can catch it if an infected animal bites or scratches them.[1] Rabies attacks the brain and nerves.[1]

Signs

  • Fever or a high temperature
  • Changes in behaviour, such as being more or less affectionate than usual
  • Going off food
  • Vomiting and diarrhoea
  • Wide pupils
  • Aggression, including biting
  • Drooling
  • Restlessness
  • Weakness in the muscles that gets worse
  • Paralysis, or not being able to move

Causes and risk factors

  • Saliva from an infected animal through a bite or scratch

What the experts say

“Serious side effects, such as anaphylaxis (severe allergic reaction), are extremely rare (less than 1 in 10,000), but if your cat does experience any side effects, speak to your vet straight away.”

If your pet is struggling to breathe, has collapsed, is having a seizure or can't stand up: go to the nearest vet now.
