how old is Chewie?
Do not attempt to give Chewie an enema at home because one kitty jerk and he will have a ruptured bowel. Instead give him two ounces of milk. It should produce a BM in less then two hours. You can give some every day until Chewie is regular.He should also eat canned food with water added to insure a proper fluid balance in his colon.You can also give him droppers of unflavored pedialyte to keep him hydrated.
Please let me know how he is doing.I will be here till midnight and happy to help further.
when was his last BM and when did he eat last?
does he seem in pain or uncomfortable?
Here is the problem.Chewis is 11 years old and cannot tolerate stress.He is already in pain and retained stool can become toxic and poison his system so al I can tell you is based on these facts if Chewie were my boy I would have him seen ASAP so he could get relief. After that you can begin the daily milk maintenence therapy and also give him cannned so he gets more fluid in his bowels.
Please let me know how he is.
