Dr. Kathy did the exploratory surgery on Precious and found she had ingested carpet fibers that had packed at the entrance to her large intestine. We have wood floors, the carpet fibers came from the cat tree. Each time the cats scratch, small pieces of carpet are shed. I am constantly sweeping them up. I never knew she was eating them and I guess I never would have thought it would have caused a problem. She also has a lot of fat build up around her insides and will probably go on special food to help eliminate this fat pad (she is 9 pounds, down a whole pound from last week,so she is not fat by any means.) This extra fat causes pressure on her intestines. The vet also suggested a lion cut to help with the ingesting of fur. She took a biopsy of something, but I failed, in my excitement, to write it down. She is coming out of the anesthetic and might come home tomorrow!!! Thank you so much for all your support, your purrs and thoughts helped get Precious and me, too, through a real trying time.
