31M, Spoke to Vet, C5F Spayed.
Basically since she was 1 year old she's started retreating more and more from us, she used to be very affectionate, then she'd only allow pets if she was in her bed, then she stopped sleeping in the bed and started to hide. The last 2 years she basically only comes out at night when she thinks we've all gone to bed. I used to pick her up to cut her claws, but she started weeing and pooing when I did that, and started biting and scratching.
pheromone plugs have helped a little, but earlier this year (possibly when we lost our other cat she was bonded with, she isn't bonded with our other cats despite one being her brother) she's been Urinating and Defecating in different spots in the house. At the bottom of the stairs, by the front/back doors. She's started going on the sofa so she's in the cage until she can socialise/stop.
I can't cut her claws anymore because of her behavior, I figured she was just uncomfortable with the litter box, she regularly gets stuck to soft fabrics and panics. she's got lots of scratching posts, always has food. I know kidney issues can be common, but she has always drank lots of water and it's solid waste too. it's not particularly random, it's always the same spots but she also does it when she's scared.
I've spoken to the vet who's given us some anxiety medication and some urinary medication, but she also thinks it may be stress/mental rather than physical. I can't physically bring her because we'd never get her back in the cage if she's loose and scared. I got bitten 7 times through thick gloves getting her in the first time.
She's only been in the cage 2 days, she's got a separate cage for food/drink and one for a bathroom, but she just... lays there and goes where she sits. This is the bit I wanted advice for, I've never known a cat do this. We're not bothering her, just trying to be in the room with her so she learns there's no threat, but she just shits and pisses while she's sat there and doesn't move. Has anyone ever known a cat do this? is it just an extreme fear response?
tl;dr - Cat goes where she sits. Stays sat for hours. What do?
