That happened to a cat that I had. About a year after she was spayed. she started coming into heat (she thought she was atleast) the vet had me put her on bith control pill for awhile. So anoying. She ended up dieing for mammary cancer probabaly from the pills. Grrrrrr!
I hope that is not the case with your girl.
As for the boy. I think you will be very happy if you neuter him. I had mine done earily hoping to avoid marking behavier around the house. So far it has worked.
