Polydactyl kittens & cats in Henderson, Nevada

Vader’s birthday is 9/7/2019. He was adopted from a pet shelter in California. He is neutered and i believe he is microchipped. I have had him since 12/23/2019. Vader loves to play hide n seek and loves to lay around in cupboards on top of blankets. He is curious about the outside, but he has been an indoor cat since I’ve had him. Unsure if he gets along with kids because i haven’t had any in the house. He has been around a Boston terrier, and after a couple of days, he gets along well enough with the dog. Since i moved into my fiancés course, Vader has been acting nervous and sort of sketched out. He hides under the bed and couch. I bought calming diffusers but they don’t seem to help. There have been a couple times he has pooped outside his litter box on top of a scratching post. I just don’t think he is happy living at this house and i want him to be happy. He will cuddle on the bed at night and purrs and loves getting brushed.
