I have a soft spot for animals, so we have a good number of indoor cats. We just moved into a 2-story house, and none of our cats have lived in one before. Within a few hours all the cats except one had went up and down the stairs with no issues. But not this one. He went up them on his own, then refused to come down. He just sat at the top of the stairs looking down and crying. So I went to pick him up to carry him down and he freaked out. I literally had to toss him down to avoid being sliced to death. So it happened again, and this time my wife went to try bringing him down as he likes her more. She did about as well as I did. So now he won't go up the stairs at all.
