Russian Blue kittens & cats in Hondo, Texas

I got gracie a few years ago from my husbands step dad. His step dad decided to de-claw her front paws (not sure why). Gracie is almost 8 years old. Gracie does get along with my lab but chooses to stay independent. I’d like to add she can get a long with other cats but only males, she will co exist with other animals. She’s a bedroom cat and prefers a small cozy space, our life has gotten crazy with having a new baby and she’s started to act out as our attention has turn towards the baby. she will pee outside her litter box and strongly dislikes all the constant noise and movement from the baby. She started to mark her territory on our bed and door mats. Which is out of character for her. At this point, i feel out of options as she won’t adapt to this new life style. We full heartedly believe she would be better off rehomed. Please feel free to ask me any questions you might have!
