The other night my cat got out for about 5 hours she was with my neighbors cat(male) since she's returned she is constantly meowing running to window as if looking for him and everywhere she goes she'll lay down with her back end slightly arched up and softly meow. I haven't had a chance to get her desexed so she has been an inside cat but snuck out . She has been like this since the morning after her return please help me out this constant behavior is sending me crazy

You've waited too long for the spaying. It sounds like she is in heat and may be pregnant now (after getting out and mating). Please get her spayed.

She was getting done next month it's easy to say get her spayed it's another to have that money to do so.

Well, in two months or so, there will be kittens at your house.

How old is she?

Not quite a year.

She's really too young for a first litter. Any chance you can get her spayed now and get yourself on an easy-payment plan?

Waiting on a phone call back from my vet to see if they will accept it being paid off
