Yes, however I would call your vet and explain the situation.
Typically a steroid injection and/or prostaglandin administration can induce abortion while preserving integrity of the uterus.
Still, I would recommend spaying her due to pet overpopulation and the subsequent euthanasia of millions of cats, but I'll leave that up to you.
Thank you, XXXXX XXXXX call our vet tomorrow, I am going to let her have one litter as I already have homes lined up for them.
Okay. One sign that she may have mated would be the absence of signs of heat.
So if she is no longer showing the normal clinical signs, I would suspect mating as cats are induced ovulators.
Which means that they will continually go into heat until mating, which will stop the heat cycle as it stimulates ovulation.
Do you any questions about that?
No I knew that thanks, XXXXX XXXXX an eye on her tonight.
Cool. Then kindly rate my service so I may know how well I assisted you today :)
