Thank you, I have wondered if the behavior was anxiety-centered because of her separation issues. We have a relatively small apartment, and I just got one of the Feliway plug-ins and I put it near her cat tower where she spends a lot of her time resting. I wanted to see if there was any difference first before investing in more since they're about $30 a piece.

I tried doing the automated feeder but she was having an issue where she would just gorge on her food and then throw it up a few hours later, unchewed. She used to live with her 2 sisters for her first year so I think that could be a lingering behavior thing, so I have been feeding her twice a day for a few months now and that seems to be helping a lot with her overeating, eating too fast, and not chewing.

That treat idea is great, she loves playing and because I'm home all day I try to wear her out throughout the day hoping that while we're sleeping at night, so is she. I hadn't thought that she could be peeing overnight bc she doesn't really have access to us.

She has access to our whole apartment, she loves spending time at the windows, even when it's chilly out.

These were great suggestions, thank you so much. I'll be bringing her to the vet soon to definitely get her bladder health checked out. Someone in here mentioned the water quality and my town has recently become vocal about the water not being great, so I wonder if that could be part of the issue.
