A stray cat gave birth to a litter of kittens, but one of them whose front legs never fully developed, didn't run as fast as his siblings, but he quickly won over his rescuers' hearts.

Meet Mouse the cat!

Mouse was born as a feral kitten. He was brought into the Best Friends Kitten Nursery in Salt Lake City along with his mom and siblings.

"The staff and volunteers were able to tame him down enough at the kitten nursery," Barbara Williamson of Best Friends Animal Society told Love Meow.

Soon they realized that Mouse was not only a little wild, he had a congenital deformity. "His front legs were not developing normally. So, Mouse was placed into foster care."

As soon as Mouse came to his foster home, he fit in almost immediately. The little tuxedo began to snuggle with the resident cat, and they quickly discovered his sweet nature and adorable personality. All it took was a little bit of love, and he recipercated in purrs and cuddles.

"He soon demonstrated that he was a brave and adventurous little guy – and admitted he liked being a house cat. Healthy, strong and at ease around others."

Mouse soon caught up in speed and strength with his siblings despite having shorter front legs. He wasn't going to let his deformity hamper him in any way.

When it was time for him to find his forever home, a lovely couple fell for this adorable guy.

"Mouse was adopted by Lana and Curtis Crichton who fell in love with him at the Salt Lake Pet Adoption Center. Now this spunky little guy is one happy and very loved kitty."

Mouse knew right away he was home!

He got a new name: Smalls.

Today, Smalls is as rambunctious as he can be. His humans love him to bits.
