> Do your vets recommend the drops instead? Well, "the drops" is a broad category. They typically recommend certain spot treatments and offer to administer it for free because the most common reason for problems is misapplication and they really do care about the health and safety of your pet. Most of these are friends or family who happen to be vets and not my pet's vet, but the same applies. > I use the collar because one of my cats did not react well to the drops. It stands to reason that even a potentially dangerous treatment could be better than no treatment at all when the standard front line treatment fails. I think there's also definitely an element of "now that you know it works and didn't instantly kill your cat maybe switching to something else introduces risk unnecessarily". It's probably best to keep following your vet's advice for your cats' specific circumstances.
