When we married, my wife introduced me to her two cats. One was very skittish, anytime anyone came to the house, the cat would hide.
The other cat was the exact opposite. Friendly to a fault. The cat would hang around the dinner table and tap us for handouts during dinner. If we did not listen, she would pop up on a chair and sit there looking at us like a guest would.
At night the cat would sleep on my arm in bed. This cat was so much like a dog should have named it FIDO. I loved that cat and miss it much but we are in no more pets (NMP) mode. Losing them both was a heart break.
My husband had "Sammy," a pound-hound. My hubby nicknamed him "the little turd." When he died....
No more pets for me either. It just hurts too much when they die. HEARTBREAK is the right word.
