I feel horrible writing this. I've had a middle aged female moggie for around 3 months, she's spayed. Lived with other cats before, very gentle and affectionate.
I'm in a small flat but she has outdoor access, though I don't have a cat flap nor do I have direct garden access from my flat so I have to be careful.
I play plenty of cat tv, give her a lot of affection and play with her.
She can be quite clingy, not in a bad way but that's just her personality. I thought for a while about getting a second cat, since she'd lived with them before. Thought about which sex, breed, age etc.
I did consider a kitten and thought maybe she'd mother it, but I know kittens can only be left a few hours initially and I didn't think I'd have the time to give around my working hours, plus I thought there was a risk of the kitten agitating her.
I ended up getting an older tomcat the other day, he's 12 and has been neutered too luckily. Very gentle, was very confident around the house, instantly roaming.
My other girl has hissed at him a couple of times. Luckily nothing else has happened between them, they mainly just look at each other. I know it's hard for her though, she won't go in the bedroom anymore and tends to stay in the corner, so I've let her outside.
I'm now wondering if I've made a mistake and that I should've left her as the only cat. I know it's only been a few days. I thought she might be bored or lonely because of how clingy she is, like following me into the toilet and everything, and I thought she might appreciate a companion.
I feel like a horrible person and an idiot. Just not sure what to do at all, I know it's only been a few days, maybe they'll get used to each other? I've kept their food and litter apart and try to keep them apart, but it's only a small flat.
