If I did, I would be haunted for the rest of my life.
I would ditch my cat without hesitation.
I'd try to leave some food, which probably wouldn't be good very long, and then it'd have to fend for itself, but that's it.
Thats the way I feel. I would be haunted by them. They have never let me down and I wouldn't let them down. No, I wouldn't leave my pets.
