Ideally, I want to brush my cats teeth, but I enjoy that they are lovebugs towards me because I
DON'T do mean things to them everyday like cram my hand in their mouth, lol!

Instead, I'm their biggest fan when I bust out the Greenies, which primarily use mechanical action to scrape teeth clean... and apparently they are super delicious, as they run and jump like their in the Olympics to get em as I toss them high up on shelves and across the room. Oh and btw, these are not in any way related to dog greenies other than that they are made by the same manufacturer. At our last checkup, the vet said their teeth and gums were very healthy, and they don't have stinky breath, but then again they are still very young so that may not be real proof of efficacy.

Regarding dental drops for their water, to avoid being wasteful I would recommend a nice ceramic fountain, but would check with the manufacturer on whether or not you'd need to remove the carbon filter by the pump if it would filter out the chemical:

Note that as long as you aren't using a very powerful reverse osmosis filter or distilled water, that the water should already have a bit of fluoride in it as well, which has some dental benefit (although technically I'm against having it in water since humans get plenty of fluoride from their toothpaste alone, but that's another debate, heh).
