Cutie has not started to make a nest, but she had fresh hay every day, so if she wants to make one, she can. I'll do some reading here to see if she needs anything else for a nest.
She has a few spots on her hind quarters that look like she's been pulling it out. I think the thickening of the dewlap is why my husband thought she was pregnant. She has put on a bit of weight, but her diet and situation have been improved, so that could be the cause of her weight gain.
I'll keep an eye on her and maybe even run her to the vet with Romeo when he goes in to be neutered later this week.
I am just so pleased with the quick responses from all of you guys. You folks have already been a tremendous help!
Thank you!
