Our cat is a stalker! Advice please...
Hi everyone, I hope someone can offer some advice. Here's the background; we have cat-sat a relative's older spayed female for years when he is on business trips. She's a quiet loner type who's never been a problem. Last year we took in a stray part Maine Coon, so he's gotten pretty big. He's a (now) neutered male. When our guest cat first came to visit, all was fine - but the second time (pre-neutering) he followed her all around the house non-stop, upsetting her to the point where we finally separated them. I don't think he was trying to upset her (he wasn't attacking or hissing or anything)- he's just a big sociable doofus who doesn't seem to understand that she just wants to be left alone.
So, this past summer we adopted two adult spayed females from the shelter. Our three cats get along great; sometimes our male and one of the females will wrestle and play but there is no fighting and they're often napping together.
On to now.... Our guest cat is back for a few weeks. We hate having to keep her separate because she doesn't get to lay in the sun, is away from us, etc. We were hoping that now that our male was more accustomed to other cats he wouldn't follow her around like an obsessive ex-boyfriend - but he still is. I really don't think he means any harm but I don't think the guest cat knows that, and is understandably a bit concerned because he's about four times her size. It's only been a few days but she's been hiding under our bed a lot (while our big oaf naps next to it), instead of last visit when she'd sit on the windowsill.
Should I leave them to work it out? Should I segregate them again? Should I give it some time? She'll be here for about two more weeks this time, and will almost certainly be back in future. Any advice would be appreciated, please!
