Yes, I have 2 ( evidently my husband didn't recall buying both!). I don't use them since it takes out the undercoat. I show my cats and even the ones I dont I want to look fluffy.
Glad I found your post here.
This may sound naive, but I comb (uneven teeth) Sasha twice daily and find only slightly matted parts are under the belly and front legs which I comb out and sometimes clip (1/2" at most) if he gets too fussy about the tugging. I remove about a thumb's length and thickness of fur each time.
I was considering buying the large Furminator, but I don't think it necessary to remove the undercoat (definitely not a show cat, but my champion, anyway). I assume it's there for a reason and compare it to down on a duck. Opinion?
Would you suggest it for use on non-show cats? He's never coughed up a hairball and only during the spring shed do I find any in his stool. His biggest hair problem is finding MY hair (down to my waist) occasionally in his stool. I meticulously pick up my hair, but every now and then, I obviously miss one and that bothers me more than his fur as it is so darn long.
