Finster
Mousey, my Siamese, used to ambush next doors yappy terrier, cruelly funny watching him circle around the garden to get behind it.
Ex wife's dog used to get its water bowl regularly topped up by the self same cat if it was too cold for it to go outdoors and spray the neighbours garage door.

Best dog mauling cat I owned when a youngster was a ferocious semi feral little tortoiseshell rescued as a kitten whom I called Mumps. Grandparents came round one Christmas with their stupid poodle which immediately ran up to the sleeping little monster and gave it a good sniff, upon being rudely awoken, Mumps realised it was a dog and slashed its nose 3 times with a right left right combination in under a second. Cue blood, yelping and distraught grandmother. Cue its young owner trying hard not to be heard laughing as he took the outraged cat and shut it in another room for the duration.
