When you're not looking, even the most feuding of furballs can be caught snuggling with each other. And some of the unlikeliest pets — big and small, cats and dogs — can end up pals. I've rounded up my fave BFFs (best furry friends), so take a look!
Boo and Buddy
Boo may be the celebrity  pup, but his pal Buddy is another too-cute Pomeranian.
Birkley and Henry
Birkley the Boxer made fast friends with Henry the Doberman/Rottweiler mix. So sweet!

Buster and Lilly
Even birds of different feathers can flock together . . . at least at nap time.

Cookie and Vivian
I love how inseparable Cookie the English Mastiff and Vivian the Cairn Terrier  are despite their size difference.
Mister and Sandwich
Community member nnoman shared pics of these sweet kitties  snuggling as kittens and then again as full-grown friends!
Oliver and Red
Another disproportionately sized pair, this Rhodesian Ridgeback and Pug  are best buds.
This pic of sweet Samoyed pups was snapped behind the scenes at this year's Westminster Dog Show .
Charlie and Razz
Look closely, there are two cats in there!
