I have one cat, my now wife has 1 dog and 2 cats.
Before we moved in together I was super worried about how my cat would react to her dog since he's never been around a dog.
Turns out my cat is totally cool with the dog and vise versa. First thing my cat did when we introduced them was rub his whole body up against her dogs snoot. It was super adorable. They will actually chase and play with each other in the back yard.
My cat, however, does not get along at all with the other cats, will hiss and sometimes swipe at them if they get too close.
My wifes black cat used to be moody but ever since we moved to a bigger place and started working from home she's been super cuddly and sweet. She will pee on things if crossed. Or if it's simply soft and on the floor. I once had to rescue her from a tree, after being let once. She spend hours lost in 100 degree heat before we discovered her stuck in the tree. She spend hours lost in 100 degree heat before we discovered her stuck in the tree. She is no longer allowed outside.
My wifes second cat is super fancy, sweet, and cuddly but gets hangry. He was jumped on my nuts many times because we are asleep and not feeding him. Fortunately lately he's been running across our heads instead, after having a vasectomy I am very pleased with this change. This cat requires a special diet and will pee on things when crossed.
My cat is the only outdoor/indoor cat, he's smart enough to never leave the property and never crosses the street but that's the full extent of his intelligence. He's a good boy who's never ever peed or pooped on anything. He is super chill but dumb as rocks. He loves being cradled like a baby.
We also have an axolotl - my wifes second cat, the nut smashing one with a special diet... he will sit next to his tank and they will just stare at each other.
We recently got a puppy, she is a whirlwind of chaos and mischief.
My wifes dog is slowly coming around to tolerating her, initially outright hated her.
She has earned a smack or two from my cat but after I scolded him for scratching her he now only paws. He is extremely patient with her... the other cats wont even get close to her.
