Heartworm: please don't skip the tablet

Pound is an indoor cat but I still give him the heartworm tablet every month. People think it is only for dogs, which is wrong. Mosquitoes come in through the balcony door in Jomtien all year round, and one bite is enough. Our vet did a test last spring and it was fine, so we keep going. The tablet costs a bit but a lot less than treating a sick cat. Set a reminder on your phone, that is what I do.
