CatDog (Seasons 1–3)

CatDog (1998–2005) is the wonderfully absurd Nickelodeon cartoon you can watch online on iFILM. The hero is two animals fused into one body, a cat's head at one end and a dog's at the other. Neither of them can ever walk away from the other.

Cat is the tidy, scheming snob with grand ideas and an empty wallet. Dog is the cheerful goofball who chases anything that moves and dives headfirst into mud. Every episode lands them in some new mess, whether the Greaser Dogs are hunting them down or one of Cat's elaborate plans collapses right on top of him. Jim Cummings and Tom Kenny, the future voice of SpongeBob, bring the mismatched brothers to life.

Created by Peter Hannan, the show became one of Nickelodeon's strangest and most memorable late-90s experiments. Its comedy runs on a simple, foolproof premise: two personalities who can't stand each other's habits and physically can't separate. A solid pick for family viewing or anyone feeling nostalgic for that era of cartoons. Stream every episode of CatDog online on iFILM.
