That's our black kitten, Bert, suckling on our orange and white kitten, Ernie. Bert is suckling Ernie's paw. I'm starting to understand why Bert is so skinny.
Beware of the kitty under the rug. Danger.
Here's Bert giving Ernie a love bite. It looks like suckling, but this time they were playing.
Ernie is trying to make friends with our older cat, Buzz. Buzz looks annoyed.
