Hello, I'm new to this site. I'm Shannon & I am a Nursing student. I also take care of my neighborhood strays. Yesterday, I had my first male neutered. He is still trying to mate with my female who won't get spayed until March. In human males, semen is stored for up to 4 months. Is it also stored in cats? Hw long do I wait before they can interact safely? I hadn't thought about this when I picked him up & the vet is closed on weekends. Thank you for all your help.
