I've had the new baby guinea pigs for almost a week. They have mites! Having informed the farm where I purchased the piggies, they gave me one dose of anti mite drops to go on back of their heads. I had to administer it myself with no experience. I pushed a drip through the fur and onto the skin on the back of the guinea pig's neck, not ear. No follow up dose given to me. I'm upset that they came to me with mites. Am I doing the right thing? Should. Take them to vets and get the farm to pay? I thought buying from someone I actually know at a local farm would be better than a large pet store chain but now I'm not so sure. Please help!
