One of the cats I look after has, her owner tells me, stress-related cystitis. She started pulling her fur out around September time, as a tomcat was prowling around outside the house, squaring up to her outside the patio doors and weeing on the doormat.
She is on Loxicom, but I thought that was just pain relief rather than something to actively target the problem. I give it to her in a bit of tuna every day. Has anyone encountered this with their cats, please? Thanks.
