Caillou learns about taking care of his beloved cat, Gilbert. And Gilbert decides he wants to have a pet, not just be one. He adopts Rexy, but decides having a pet is too much work. Caillou also discovers the rigors of responsibility. First, he comforts Gilbert during a trip to the vet for his shot. Later, when Gilbert is stranded up a tree, Caillou rallies the fire brigade to his rescue. He also plays detective to find the missing Gilbert when the cat disappears (napping in Caillou’s bed!). And he plays diplomat, too, when Gilbert’s resistance to children’s games forces Caillou to figure out kitty games that his pet much prefers.

After a segment from the show in which Gilbert was taken to the vet and didn't like it, Rexy asks Gilbert why he wants to take him to the vet if it was so dislikeable.
