My name is Princess Mustache!

We got her from a friend who's mother left her in the house she got alone. She's around 5 years old. She's so sweet and loves to be pet/butts her head on any surface for pets. She has had some dental work done due to an issue she had before we got her. 12 teeth were removed but she seems to eat dry food just fine. We give her wet food as well to ease the strain on her teeth. We are looking to rehome because after 4 months, she is not getting along with the other cat we've had for years. Our friend had kids and we think she was okay with them. I'm not sure about dogs but for sure not okay with other cats. She's very sweet to people but is wary and growls at outside noises (living in an apartment there were neighbors going in and out). The outside noises seem to not bother her too much anymore.
