Hi, I'm curious whether anyone has any advice or tips on how to deal with ticks. We live rurally and have three cats; one in particular is bringing lots of ticks back into the house with him at the moment. They have a regular tick and flea treatment (from the vet, not an aromatherapy-type one) and vet has recommended collars as a next step if there's no improvement. The ticks don't seem to be dying despite the treatment, and we found one on our toddler today, luckily before it bit him. Am I missing something obvious here? Keeping the cats indoors isn't an option but if any of you have tips I'd be grateful.
