Hello, have not posted in a while . I have a 16 year old cat, and for the past month or so he has not been himself. He has slowed down quite a bit and I can see in the past few weeks he looked as though he either had arthritis in his legs, hips or both. He also stopped pooping for 3 plus days, He eats and drinks and pees o.k just the lethargic symptom and the poop problem and surely pain. I took him to the vet thurs he checked for constipation and blockage, and he seems to be o,k in those areas .Took x ray his intestines look good but the vet did say arthritis and gave us gabapentin. .05 to start and up the dose in 7 days, he also says to give 1/4 teaspoon of MiraLAX twice a day . Well, that was Thursday no poo Friday no poo but this morning explosive diarrhea Poor thing was so loaded he feel in it,lucky me,,oooh well. We cleaned him up but now the vet is gone till Monday and i wonder if i should give more laxative or wait till vet is in on Monday to ask? also he seems to be really doped up, i am worried about upping the dose he is already not walking very good with the arthritis and dose he is on. Do you think hold off on the laxative till Monday? Just wondering. Thanks,,,,
