Virbac CET Feline Chews

Anybody have any experience with these? Considering getting some for my cat. It's the only dental treat without carbs.

I've noted that they are considered favourably by people on the forum. I would also love to try them but they don't sell them where I live.  I have tried the toothpaste but my cats didn't like that particular flavour. 

Here's a link to a thread which talks about other things you may wish to consider as well. 

I've tried them before. The chews are pretty large so a cat has to really chew and gnaw on it to break it up into small enough pieces to swallow. It works better than something tiny like Greenies, IMO.
