They own pets and arn’t use to this yet? This a joke that should have been around a friend, not the owners.
Preferably on the weekend. Kitty climbs in victim’s lap, owner says she likes you. Start cleaning and it’s she trusts you. Start there and it’s… well cats are cats. With elaborate hand frustration. I’d close with “How do I make her trust me a little less?” Least for the cat. And unexpected slurp from puppy would be followed by “what was he doing?”.
