Soft for my kitty's teeth
I have six cats and each get their own tooth brush. Each cat is noted with a different color and they are small enough for kitties teeth and not harsh. Bristles are soft so kitty gums do not get irritated.

Nice for small dogs
These little toothbrushes are perfect for small breed dogs. They don’t seem to mind getting their teeth brushed and they do an adequate job as long as you don’t wait in between too long.

Finally a super soft toothbrush made for small dogs...
The texture of the brush is very different from others I’ve tried before. It’s very soft but solid. If you’re looking for a small gentle brush, please don’t hesitate to give it a try.

Bristles are soft and dense but a little too long for cats but still the best so far.
Very good brushes with dense but soft bristles. The pros are the excellent bristles as they are abrasive enough to actually clean my kitty's teeth. I have to work really fast to clean her teeth. These bristles make the cleaning a bit more efficient compared to the silicone bristles that I have used prior to this. The cons of these brushes is that the length of the bristles are too long. These are better suited for dogs, but for cats, their mouth is a lot smaller. There isn't a lot of space to insert this brush between the inside of my kitty's cheeks and the side teeth. I wish the bristles were shorter. There is no way for me to trim them shorter because then the bristles will no longer be soft. Having said that, these pair of brushes are still the bets so far that I have used. The bristles really makes all the difference.
