I have a 14 yr old female cat. She has had dry food all of her life. She has always been healthy and active. A few weeks ago she starting meowing strangely and then jumped on the bed where she strained to go poop. She went on the bed which was large and hard. I realized she was constipated and started to find things to help her. I have given her hairball remedy which hasn't really seemed to help. She hates pumpkin. I finally found some canned food that she enjoys. Problem is she is still going on the bed. Fortunately so far it has not been loose so I have been able to clean it up fairly easily as well as washing the bedding as needed. Any ideas how to get her to go in the litterbox again? She does pee in the box. Also any other ideas to help her with the constipation? She does not go every day. Thanks.
