I think the logic here is supposed to be something like:

more knowledge = more complex brain

as you need to “store” the knowledge somewhere.

I don’t say thats how it works but i can somehow see where OP is coming from.

How about a cat of similar age? Ask for a social one, as he seems to like to cuddle with other cats. Also maybe one with a similar activity level (e.g. a Siamese might be to much energy for yours). But in the end you know yourcat best and need to try it out.

Also think about what you want. They should be somewhat compatible, yes, but its okay for you to want a cat to play and cuddle with, too.

So decide what you need and want, trust the people working at the shelter and your gut on this one.

Good look finding your next family member.

The only time i cried harder was while playing RiME, and part of it was how unexpected it was. That spiritfarer got to me was kind of expected from the start, still dived in head first.

Oh, thanks for pointing that out! Thought it was indeed a blep.
