Sure they did. But Kristy took really care of Tyson (the name of the pet given by Dima, the ex-boyfriend), she loves animals as we know. Kaley cried when the hamster was sick, tried to find a pet doctor in the middle of the night, Kristy was pissed and came at 6 AM to see whether he was still alive but he was already dead. Kami didn't seem to care a lot when she came back, a few hours later.
