Hi I got it from the vets today as I'd heard other liquids have killed their rabbits. Thought it was about £15 and would last a few months for both my rabbits. Just read the instructions and it's one application! Surley there's a cheaper product? I got a spray for my Guinea Pigs (Johnsons) that kills fleas, etc and protects against flies. It was about £4 for months worth. They both seem fine when I use it but wasn't sure about using on the rabbits as I've heard horror stories. Is there a product people can reccomend?
