I'm a bit concerned about this kitten. She was out of a litter of 3 from our barn cat, who was hit by a car about 2 weeks after the kittens were born. We bottle fed pet formula and lost 2 of the 3 to fading kitten syndrome. My concerns are that she has 3 feet with only 3 claws and 1 foot with 4. She also appears to not be growing at a normal rate, she's about the size of a 2 week old. All of her skills seem right on target for her age. I'm definitely ok with having a special needs kitten but I'm still very concerned.
