Can I just tell you how many times i have been in this situation???? uggg Its so hard! I usually bring the cat home and keep in the garage....and I take to the vet. i have homed 2 in the last year.....It just depends on if your willing to take the time or not really (and the $$ of course) It's not your responsibility nor should you feel guilty if you chose to not help the cat. I can tell you tho....Its a wonderful feeling when you do help. Both cats are in friends of mines homes and are very well cared for. I hope you feel better as I can tell its tugging at your heart....Im sorry your going thru this and wish you all the best.
