I am very concerned about our outdoor environment, not the other animals (as they are all treated). We actually live in the middle of the woods and they are tons of fleas, lice, ticks and so on. I really want to bring the guineas outside during the summer, but I don't know how I will protect them from all of these. We also have lots of ants (mostly red and flying ones) and I was wondering if those would be a problem for the guinea pigs???
Either way, even if I decide to use the advantage, it will not be for at least another 3 months, so I plan to research this as much as I can and talk to my vet about it. The reason that I am so open to this is because we have a pretty large supply of Advantage, so it would not cost me anything extra to protect our piggies, but I do want to learn more about it first.
