The Monster in 3-B / Cat-Tastrophe

S1 E2: The beginning of the new school year brings new neighbors for the Howards. The animals excitedly wonder if they have a pet...until they're alarmed by a strange wailing noise coming from the apartment. Rumors of a monster are fed by the discovery of an enormous tooth and the disappearance of Flo. When Clifford finally meets the friendly new family, he finds that all his fears of them housing a "monster" are unfounded. In the end, Clifford and the gang realize that you should get to know people before you decide what they're like. The kittens, Flo and Zo, are staying with the Howards while their owner is away for the weekend. Clifford wants to be a good host but the kittens are not the most considerate house guests. They make a mess and don’t clean up after themselves. They’re rude about food. And worst of all they break Clifford’s favorite toy in the whole world and don’t apologize. Clifford’s feelings are hurt big time but Flo and Zo don’t comprehend their mistake until they see how upset Clifford is. Flo and Zo apologize and help set things straight.
