Obligatory follow up since you are all amazing

Meet Nye!

I want to start this post out with a thanks to all of you from this community for the reassurance and advice, had I never came here I would have never met this wonderful kitten!

We adopted her at an estimated age of over a year. We confirmed with the provided documentation that she had all the necessary vaccinations and were assured all of their adoptees were spayed. Since then she has slipped right into routine, we’re coming up on three weeks now and from what I consider she’s part of the family now.

Actual question

Today she was exhibiting very interesting behavior, meowing constantly, rolling around and rubbing up against everything, and sticking her butt up in the air. We reached out to the humane society we had adopted her from and they marked her as spayed but upon further inspection noted her intake didn’t state if she had been already or not.

Now for the question, to spay or not? She is handling it well, exceptionally affectionate and a bit needy but okay otherwise, at least relative to what we hear from others. She’s an indoor cat, so pregnancy isn’t a concern, but apart from that what are the reasons for or against taking her to be spayed?
