@farmerman,
I support everything you wrote 100%. Bonkers my dear (but deceased) 18 lb Maine Coon cat, had a 'lion cut' every summer. He hated being groomed, though I could brush him alot at top of his head, back and shoulders. His chest, underarms and belly were where all the trouble was. When it matted up, sometimes it was impossible.
Laxatone worked if iused regularly (1x to 2x wk as preventative and 3-4x when it was really bad.
After the first year I first got him (2yrs old), he got so clogged up that the vet had to do an endoscopic ($$$) exam to get 2 massive fur balls out that wouldn't pass. He was uptight 'cause I had jsut gotten him a playmate - a new 7 wk old kitten. He was not happy. However I learned to groom him regularly after that episode.
Hope this helps somone save a kitty from getting matts and some grief.
