I'm so sorry to hear that you and your cat have been having a such a rough week. I've only experienced this with my RB Pepper and he only needed 1 kitty enema. He was then put on lactulose and it kept him regular. I think I only fed him dry at the time. My vet never told me to change his diet.

I agree that canned pumpkin or even squash if you can't get pumpkin is a great way to keep your cat regular. I've noticed that since I've been feeding more canned food to my cats, that they now have fewer hairballs and my oldest cat Storm,he'll be 15 in Jan., doesn't get constipated like he sometimes used to. They are on a grain free diet and eat canned Wellness and a few other grain free canned foods and also some Wellness Core dry food. Good luck.
