The main reason we all think it is odd is that it is making things harder on you and Makosi, having to do so many trips. As I foster, my vets have always waived a pre-op check a day before, and do everything on the day for me. My other reason for being anxious is that while it is only days between, there is that risk she will get out - the amount of times I read on forums that 'my cat can't get out' yet they end up pregnant is unbelievable, it is a daily occurence at times - and I know how easy it is to let cats out accidentally myself. Plus, there is a risk of pyometra the longer she is left unspayed, and this can happen weeks after a heat. Plus, males can produce sperm for anything up to 6 weeks after a neuter, so depending on when he was done, there is a chance that is why he is bothering her. We are only thinking about Makosi's health and wellbeing, however it may come across.
