With so many cats there's no way we can board (except the needy ones). We hire a vet tech from our vets office to come in twice a day and look in on things. This really works well since they're already familiar with the cats, they know what to look for as far as illness etc., and they've even sat and trimmed all their claws for us while they visited with them. Plus the fact we can thoroughly trust them being in our home.
