Pets 'are' family members....and all animals are capable of harming --in the right circumstances. If a person came over and grabbed my cats tail and it bit them, I'm not blaming my cat. I blame the person.
Only the deluded think that pets are "family members".
Pets are domesticated ANIMALS. They can be affectionate, warm, loving and all that mushy stuff, but they are no more than animals.
I tell you this NOT because I'm a heartless critter hating wretch, but for your own good. It's a PET, not a PERSON.
For your edification, I am writing this with my cat purring on my lap, one of the (3)tarantulas has realized there's a cricket in her cage and is on the prowl, the budgies are chirping up a storm, the hamster is sound asleep, and there is 275lbs in 3 dogs all curled up on the sofas in the living room 10 feet behind me.
I weep when I lose a critter, but they're NOT FAMILY.
