cat war

a conflict between two housemates owning separate cats, brought on by these cats not getting along. Aggressions range from petty arguments between roommates, to outright forcing one roommate to pay a hefty vet bill due because their cat gave the other person's cat fleas.

Dude, I'm sorry my cat Snuggles pissed all over your cat Tigger's food dish, but do we really have to get into a cat war over this?
