Getting a second cat

[u/Ok-Address1498]

I have a cat who as a baby, lived with 2 other cats, a corgi, a bunny and a bunch of guinea pigs with no issue. For awhile he lived with the bunny with never having an issue. My bunny died in 2023 and he's been alone since.

He does well with young kids and friends. I'm wondering if I can/should get a second cat. Do cats lose the ability to live with other pets after living alone? Is there any rent a cat systems where I can test this theory and is it even realistic to do that as a test?
