The relationship that can form between dogs and cats is really something special. They may be stereotypical enemies, but anyone who has both a dog and a cat that live together can tell you that they're sometimes the best of friends.

One small Maltese-looking pooch happened to be BFFs with the family cat. Their close relationship continued, even up until the cat gave birth to a litter of kittens!

Their owner shared on YouTube that the dog and cat are inseparable.

She said: "I tell my dog always that the cat is his sister and they are like brother [sic] & sister! They can not live without each other."

The two constantly play together and spend time together, just like family.

You can watch them in action in the video below:

Of course, being friends with a cat is one thing. Adding kittens to the mix is a whole other ballgame.

When the cat got pregnant and gave birth to some kittens, the dog had a chance to meet the kittens and it was too cute!
