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. In the puppet segments, Gilbert chains Rexy to a leash and dubs him his "pet dinosaur." When Rexy sneezes, Gilbert notes that sick pets are taken to the vet. 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. Gilbert explains about how the vet is an animal doctor. Eventually, Teddy tells Rexy that he should tell Gilbert he doesn't want to be a pet anymore. Rexy, however, actually likes being a pet. He wakes up Gilbert and tells him he wants to go for a walk. Gilbert decides that he doesn't want to have a pet anymore, so Rexy tries to enlist Teddy, but he won't take the job. Then, Caillou calls out. He's looking for Rexy and Teddy. Meanwhile, the main portion of the show focuses on pets, specifically Gilbert, since he's Caillou's only pet. "The Cat's Meow" (A42 wip title: "Gilbert Goes to the Vet") It's time for Gilbert to go to the vet, but Caillou can't find him anywhere. Mommy finds him and the narrator notes that Gilbert doesn't like to ride in the car. In the car, Gilbert gets out of his box and hides. At the vet's, Caillou meets Sarah. Her cat Ollie is having his teeth cleaned. The vet examines Gilbert and declares everything fine. The vet gives Gilbert his yearly shots, having Caillou pet him to keep him calm. Gilbert runs off, ending the segment. "Caillou to the Rescue" (A42 wip title: "Caillou the Lion Tamer, or Firefighter") Caillou tries to teach Gilbert tricks like a lion tamer, but Gilbert is more interested in chasing butterflies. When a dog on a leash approaches him, he gets scared and races up a tree. Caillou tries to lure him down with his favorite toy mouse, but then notices how high up he is and runs to get his Dad's help. Dad gets a ladder, but it's not tall enough to reach Gilbert. He calls the fire department and when the firefighters get there, Dad recognizes an old friend of his who he played with when he was a kid, Eric. The firefighters set up a ladder and Gilbert is retrieved successfully. Gilbert proceeds to show his gratitude by running off. Caillou is invited for a tour of the firestation and rides in the firetruck. At the firestation, Caillou meets Sparky, their dalmatian, who helps them sniff for fires. Finally, the firestation's alarm sounds and the firefighters have to leave. Back at home, Caillou tells Gilbert that he's saved him and notes that Gilbert should be glad he's a firefighter.
