People buy a cat and think, 'Oh that's a beautiful collar. I'll put that on,' but that doesn't make them a responsible pet owner.

Take one female cat over a seven-year period. If all the kittens survived and bred, she would be responsible for 21,000 cats - they are such prolific breeders: you can see how important it is to neuter.

People simply shouldn't buy puppies without a breeding certificate.

On collar wounds, we normally manage to save them, but they can take weeks to heal because they're so deep, and they sort of grow into the flesh under the arm.

It's the bedsit culture: people get a cat, and then, in a few months, when they move on or go travelling, they just throw the animal out. It's so discouraging.

Multiple cat households are a good thing.
