Sal,
I can no longer treat my animals (4 cats, 1 dog) for fleas and ticks monthly and getting the family to help is a pain also. We live next to woods full of deer, DH and the dog both got Lyme's at the same time following a walk in the woods, Bean and dog ticks fall off animals in house all the time, so these pet meds are necessary. This is hard stuff, I feel your pain. I absolutely can't do it, and nagging the others shouldn't be so hard! But it is! I set everything up but still have to badger with all my nagging skills to get it done. I feel your pain.
