This is probably one of the best products to hit the veterinary market in a long time. It's a spot on that treats fleas, ticks, sarcoptic mange, ear mites, round worm, whipworm and hookworm. It does NOT kill tapeworm. It's a great wormer for cats which are difficult to pill. May also be a really good option for dogs and cats with ear mites that won't let you clean their ears. It's licensed for use against demodex but I have heard some people claim it doesn't work that well for demodectic mange. It's a tad pricey, but overall well worth it. You really are getting what you pay for.

Pros: Spot on kills fleas ticks AND worms

Cons: expensive
