Hello. I am trying to get more information from someone who posted on August 8, 2008, regarding a 15-year-old cat who was healthy one day and terribly sick with a limp the next. The EXACT thing has happened to my cat. He has been successfully being treated for megacolon for 2 1/2 years, went to the vet for a check up and the next day was LIMPING. He hasn’t been the same since. Blood tests and x-rays show everything to be normal. The vet seems to think it may be nerve related. Please help.
