Dew Claw Cat Back. He is eating and drinking. It is quite simple to identify a nail growth in cat’s paw, it is enough to observe the behavior of the animal.
Check out this video to see this in action. I don't know it is something wrong with her claw or if it simply something getting stuck in her claws but i trimmed my cat's nails for the first time (she was recently adopted) and noticed that some nails had a grey chalky substance built up under them. A new toenail will grow back within several months.
With breeding and cross breeding, different dewclaws act in different ways.
Dew claws are more common on the front paws than the back, but this many have them on both. My cat manytoes has dew claws on the back too, and one of them has 2 separate perfect claws coming out of it.its particularly unusual to have only the rear paws affected If not, you will feel a nail, just like a dog's. Remember to trim these as they are not worn down when the cat scratches and can grow in a circle, growing into the foot.
