I've noticed that my cat has become increasingly constipated. We put him outside, he digs to make a poop, and nothing came out. This happened 5 times yesterday. Before receiving his diagnosis of feline diabetes an x-ray revealed that he was severely constipated. But after receiving insulin and becoming re-hydrated he began to pass stools on a regular basis. But now, it seems he is constipated again. Our vet spoke about an overnight visit or something along those lines to remove the impacted feces. But I've read online (and here) about uses of laxatives (like miralax) and their success. Are non-invasive methods usually recommended first? What do you suggest? Thanks! confused_cat UPDATE: Yesterday Spencer started acting funny, eating less. Later in the night, I felt him guarding/flinching his stomach when I held him. Now in the morning he's refusing to eat again and guarding. No vomiting. I don't think I should give him Miralax if he's not eating? He asked to go outside, he went outside walked around a lot, smelling things. He didn't even want to come back inside. I took him in to try and feed again, even his favorite ham. Did not want it. Well he licked his lips but didn't take a bite. He's resting now and purring. When I pet him and put pressure on his ribcage, I feel him recoil/guard. I really don't know what this is. What could this be?!
