Lilly the kitten has become very attached to the smallest person in her family. She won't leave his side.

When he is taking a bath, she sits there.

"Our kitten Lilly considers our son her litter mate and follows him everywhere she can," reddit user MsSandwichmaker said.

"She has to sleep, eat, play, and be everywhere with him. Without him she is very depressing and sad. If she can see him but cannot be with him she howls and cries for him."

When he is playing in the bathroom, she tags along.

Gotta recharge for more mischief!

He offers Lilly a fishy when they hang out in the bedroom.

When he naps, Lilly snuggles up to him.

Updates! Lilly is all grown up now.

They are still each other's best friend!
