i give it to both my dog and the two cats. (they do have a seperate version for cats, but the one for all animals works fine for them as well)
It has really helped the dog. Her back teeth are looking sooooo much cleaner than they used too. Now she only has a tiny bit of staining on her canines.
With one cat - he only has his fangs and the tiny corncob teeth, but those look amazing
The other cat's teeth look in pretty good condition after having used it as well.
I have tried to brush all three of mine.... and they do let me... but i think plaque off seems to work much better.... and is easier to administer....
i also try to give them raw food/chicken wing, and the toothless cat is much better at figuring out what to do than the one with her teeth intact! (obvs the dog is the best at figuring out what to do, and is always on full alert should there be an oppurtunity of stealing......
