Cat spay and males still want to mount her

Question
I just had my female (5months old) spay one week ago.  She finally went outside yesterday, and both males tried to mount her, and she appeared to be ok with it.  How long will this last?  Should I keep her inside for a while, as I don't want her to hurt herself too soon after the surgery.

Answer
Dale,

First off, she may still have high hormone levels as it takes a few weeks for those hormones to dissipate.  Secondly horny male cats will want to breed to anything.  She may look at their behaviors as normal play.

I would be concerned about the stitches coming out, so keeping her in until the stitches are removed or get reabsorbed (10 days to 2 weeks after surgery) would, probably, be a very good idea.
