Hello, I'm new. I have a Male cat who is just a little over a year old. He has been nutered for a long time now. We took in a stray female who was nearly starved, and uncared for. It took us a few months over the summer to get them used to each other. Now the female is inside. She has gone onto heat. Can this cause behavioral problems with my male? Or will all be okay since he is nutered? Concerned. Thank you.
