Why you're as important as the vet to your cat's health
You know your cat better than anyone else and, if you're at all concerned, you shouldn't hesitate to pick up the phone to your vet. It's always better to be safe than sorry and no vet will mind a false alarm.
When to call the vet
Call your vet if you notice any of the following:
Loss of appetite
Diarrhoea or constipation
Coughing, wheezing or difficulty breathing
Dirty eyes or ears
Lethargy, tiredness or less active
Excessive scratching or very red skin
Difficulty passing urine
Crying in pain or mewing
Swollen legs or joints
Anything else that worries you.
The last of these is important.
