Trouble is Kaz, colitis is painful, so it frightens them and maybe they associate it with food. All you can do is keep trying I guess, or back to the vet?
Mick was up with her last night, tonight I'm going to try to stay awake to watch her. She's really weak. I waited until B went upstairs to put her laundry away and have had a good cry.
I know just how you feel Kaz, when Minnie was so ill it got so that I had to go to bed, but I dreaded going down in the morning. I still spend a while every night giving her a cuddle and saying I'll see her in the morning...
