Our beloved toothless kitty Bub was just 8 weeks old when she came to her new home. "BUB is one of a kind cat, rescued as the runt of an otherwise feral litter," Bub's human dad Mike Bridavsky.

"BUB was 8 weeks old, weighed about 8 ounces, and was overflowing with pure space magic," said Mike. Watch BUB in action:

"A half-pound BABY BUB's first day at home, three years ago," said Mike via instagram.

"This is the first time I met BUB, right before taking her home. Three years later, despite all odds, BUB has relearned how to walk, run and jump, written a book, starred in her own movie and TV special, and raised close to $200,000 for animals in need."

Happy Bub!
