I was at the vets yesterday and the tech answered the phone and was talking about tape worms. I learned something new. Humans can't get tapeworms from animals because animals have to ingest the host to get them. The tapeworms humans do get is a different worm than what animals get. My dogs get monthly wormers for about 7 months of the year but my cats  sometimes get tapeworm(yuck). Just thought it was an interesting fact to pass on. Makes me feel a bit better when I see those ugly things!
