I took in a stray about a month ago now. Things are going fabulously and she's integrated into our home nicely. The problem is she won't shut-up and I can't decide if she's in heat. I mean at first it was understandable because I kept her segregated in a bedroom, but now she'll meow for 10 minutes straight for no apparent reason. I don't notice any other signs and thank god she never tries to get out. Bottom line is I don't want to spend a several hundred dollars for a spay she doesn't need. Does anyone have any ideas on how to differentiate a very talkative cat from one in heat. She's a maine coon from the looks of her. Thanks!
