I have a young cat, who is currently 12 months old. I have had no health problems with her since about 2 months ago.

Every three to four weeks she goes through a stage of Meiow a lot and crouching a lot and her back legs seem to kick constandly, This continues for about 2 days and then goes , and she seems normal again.

Not sure if this is a heath problem as she seems fine generally in herself she eats and drinks fine, and she uses the litter tray fine.

I thought it could be the fact that she hasn't been neutered?

Any advice or has anyone had this same problem??
