Story
Cat is about 10 years old. I am really hoping that she can be adopted into a home that has time to spend with them. Vet comfirmed that this cat is intersex, this is why other cats tend to not like her.

Story
I’m looking for a loving, patient home for my 4-year-old cat, Theodora. She is spayed, fully housebroken, and healthy. Theo is very timid and prefers to stay hidden most of the time, especially in busy or loud environments. She isn’t aggressive at all — just shy and sensitive. Theo will do best in a quiet, low-traffic home with someone who understands that she’ll need time to adjust and warm up at her own pace. Once she feels safe, she’s a very sweet, gentle girl. This is not an easy decision, and my priority is finding the right fit where she can feel secure and loved. Please message me if you think you could offer her that kind of home. 🖤

Story
Unfortunately, we need to rehome one of our cats. His name is Passepartout or “Pass” and he is a 2 year old half Tonkinese/tabby mix. We rescued Pass when he was a little kitten. But unfortunately he bites our kid and we have a new child on the way.. we can’t trust him anymore with children around.. He is very friendly and house trained, but is untrustworthy with children and has bitten children a few times when they play too rough or when he is petted while he is on his back or nested in his corner. He is current on all vaccines and has no medical issues. We are looking for a person or family with adult kids to rehome him and have a better life.

Story
I took in Spidey at 3 months old, and he quickly adapted from the barn cat life to a chill indoor life with another cat that I owned. Now, he's almost 3 years old. Spidey loves cuddling with EVERYONE! Other cats, dogs, or his favorite human. When he's not cuddling, he's playing with toy mice or walking around with his favorite stuffed animal. Because he needs so much attention and loves to play, he fits best in a home with other animals.
