Catsitting advice

[DanHumphreyIsA]

My relative is going away for two weeks in October and I will be looking after her cat.
The plan was for the cat to stay in her house (as I have three otherwise).
However I'm not sure how much time I should spend with her. I'm feeling very guilty about her being alone for long periods of time.
She's mainly indoors, only nips out for 10 minutes once or twice a day. My three are never alone for more than 2-3 hours as I work nights and DH works days so someones always in bar groceries, visiting family etc so I don't know what's normal.

I'm wondering whether I should just bring her to ours? Would it be cruel to keep her in one bedroom for two weeks? We have 2 spare rooms, one which is a box room, with the litter boxes and one is a larger room so plenty of space for food, bed and litter tray.
2 of my cats are outdoor, so I could give her this time to wander around the house. 1 of my cats is indoor, not aggressive at all just curious, she'll have a sniff of any newcomers feet/bags and then flounce off to her den..
However, relatives cat can be abit scratchy/bitey if you stroke her one time too many

Realistically, if she stays in her own house, I could probably only spend 2-3 hours there, straight after or just before work, without burning myself out.

Would it be better/enough to leave her there and visit once, sometimes twice a day or leave her in our spare room?

I think it's better for her to stay in her own house, with you popping in. Cats are too territorial to mix luke that.
2-3 hrs wpuld be plenty, and more than she'd get in a cattery.

A cat will always be happier in its own familiar surroundings. A couple of visits a day, as long as you make time for a play and a groom should be fine.

Agree with pp. Far kinder to be alone in her own surroundings than locked in a strange bedroom/around other unfamiliar cats.

I should add I see her almost daily, so she knows me and loves to nuzzle into my armpit😂 so it wouldn't be completely unfamiliar. But I see about the surroundings.
Think I'll just leave her there then and visit.

Would I be ok to not let her out for these two weeks? She does only go out for a very short time, most of the time she hides when the front/back doors are open lol.
But i'm worried on the off chance she'll want to go off for a bit longer and if I have to get back home/get to work I wont manage to find her in time.

I also agree. She will be much, much happier staying where she is. And yes it's fine not to let her out in the circumstances.

Thanks all
