Like many cats in a multi-cat household, Ivan and Natasha live together bound by a mutually agreed-upon peace treaty. Indeed, theres an occasional breach when one crosses the others claim to a toy or cherished napping spot but that doesnt terminate treaty relations. However, there is one major treaty violation that makes it clear that this isnt a non-aggression pact: the veterinary visit. It doesnt matter if they go to the vet together or separately. Once back home, there are no consoling purrs. Natasha lights into Ivan with a barrage of aggressive behaviors as if she doesnt recognize her peace partner.
