Oh wow, this is soooooo adorable!
I really do not know where the rumor comes from that dogs and cats do not like each other. Look at these baby ones.
They are curious about each other. They check out each other out at the beginning because they can tell the other 4-legged ones look different. Then they forget about it, and start playing together!
They even share their food and lick each other. The first time they meet!
