Wash children's hands before eating. If feasible, leave shoes at the door. Solvents are just as bad for your pet as for you. Most flavored pet foods are polluted with solvents such as carbon tetrachloride, benzene, isopropyl alcohol, wood alcohol, etc. Don't buy flavored pet food.
Pets add a great deal to human lives.
Get rid of the parasites, not the pets, unless you are ill.
