Footrot Flats is a cartoon strip by Murray Ball, a New Zealander. The big boofy cat in that - a farm cat - is scary! Big & hairy and scary, like a charging boar. More like a pit bull terrier than a cat.

I don't think there is an online site. There are books available.

The cartoon is centred around "The Dog", a border collie on a farm in New Zealand, and his human, called Wal, and assorted animal and human characters. It's been around for years. Very clever, very funny. One of my favourites.

Example: Wal and the Dog are at the local agricultural show. Wal stops at a Hot Dog stand. The dog reads the sign and wonders what a hot dog is. Just at that moment Wal takes the hot dog out of the bun, holds it above his mouth and starts to eat it. The dog exclaims: I don't want to know!
