- Bengal kitten Winston mistakenly eating kitty litter while his siblings eat raw meat.
- Pip the hedgehog hoglet climbing up people's pants.

- One of the Sphynx kittens stumbling around, trying to find a place to nurse from his mom. He does eventually find one, but it was hard because, since he's so little, his eyes aren't open yet. At one point, he sticks his nose into what turns out to be his mom's paw.
Narrator: No milk there!
