Stress colitis and cystitis

Hello vets, my cat Evie has recently started eating like she is starving and will come and take food off of my plate and she never used to do this until recent. I took her to the vets last month and she was wormed, but a day after she was bum surfing and there was no worms present or anything in the cat litter or on the floor and she only started eating like this after. I feed her James Wellbeloved cat food and breakies as my vet said she has stress colitis and said this is the best food for her. Evie also has started meowing horribly when she wakes up at night and it terrifies me and she has been weeing on the carpet again and wanting to be near me more than usual as normally she dont wanna sit with me. I took her to the vets and they said she has stress colitis but I want to find the route cause as she dont seem to be getting any better and I've spent loads of money on trying to get her better. And also keeps getting cystitis as well. Evie is highly nervous and likes everything to stay the same so same people come who she knows as if not she will hide for hours even when they have gone and she also ate art putty about a month ago but her symptoms have been like this since way before then, I dont think shes passed the putty but how will I know ? *I have also had her spayed, her injections done and many vet trips due to her keep being I'll since I have got her and she is 2 years old*

Hello!  Evie is not my patient, so I will answer for a general stressed cat. Cystitis in particular can be very commonly linked to stress.  Cats do not show social stress signals as easily as humans and dogs, who have evolved body language and (in humans' case) spoken language to communicate with other members of their 'group.' Indeed, cats split into 'territories' even within the same household (if there is more than one cat in your house, you may be able to map this).  When their territory is threatened, they tend to either physically avoid conflict, or to stand their ground and fight, having evolved very few subtle 'in between' or 'warning' social graces to settle things. A site to urinate in their own territory is very important to a cat - as important as a seat at the family dining-table is to many humans.  Something as simple as someone leaving a strange object like a suitcase near a favourite litter-tray, or a changing of cat-litter, or it being cold outside, or too much human activity near a toilet site, or having to access the toilet by passing through another cats' 'territory,' can be enough for a cat to 'go off' their urine site or avoid using it, holding their urine for longer periods, causing cystitis. To find out more about this, search for cystitis and feline urine habits in our blog.  It is also something to ask your vet about.  Sarah Caney, one of our writers on this subject, has her own website, Vet Professionals, which may be useful.  In general, it helps to have a good choice of multiple litter trays available to each cat, within their own chosen territory (place to hang out). However, it's also worth mentioning that eating 'as if she's starving' can also be a serious clinical sign in a cat.  You seem to imply that your vet knows about all these signs but if they don't, you should think about hyperthyroidism or diabetes or cancer or other such concerns and Evie should be checked out urgently again just in case. Illness can, of course, contribute to stress and some illnesses cause excessive urination themselves. Best of luck.
