How do you tell your friend you don't want to stay at her house cause of her cats?

I'm not allergic to cats, I've just not been a fan of them.
The last few times I've slept at my friends house, the cats kept jumping up on the bed & walking all over me.
She has 2.
They make me really uncomfortable & it was hard to sleep.
I don't want to upset her but I don't like sleeping at people's houses if they have them.
What can I say to not hurt her feelings?
This is the second time I've stayed, but I can't do it for another time

I've only known her for 4 months so it's a bit awkward telling a new friend
