Just wanted to post and say that I'm so sorry to hear about Oscar.
I was hoping to see that he was doing well after surgery but the way it sounds, this was probably best for him. No more pain.
Naya, you did such a great thing by taking care of him. Like someone posted earlier, he could of died the day the dog attacked him yet you took him in and showed him the best life he could of ever imagined after the day of his attack..... You should be very proud of the job you did making Oscar a HAPPY kitten in his short time. You took such good care of him. Just remember, he couldn't have had it any better with anyone but you. You gave him the chance to be a playful fun kitty who will be loved and dearly missed by many, especially from all the posters here on TCS. Thanks for updating and letting us get to know Oscar while he was here!! You did a wonderful thing with him!!
Please remember that even though it hurts horribly now.... I know you would do it all again if you had to!!
~RIP little buddy~
