We wanted to mention another word that starts with the letter H, Heartworms. This is a very scary word.
You may not know but my sister Tuiren had Heartworms when she came to live with us. She tells about her experience here.
There are Heartworm preventives for both doggies and cats and I sincerely hope that you give your dog or cat one every month. Currently there is no treatment for cats if they get Heartworms.
