Help clarence receive medical attention he needs!!

I have had my kitty Clarence since April of 2018. He has been my best friend since day one. He was there for me when I had just gotten out of an abusive relationship last year and he was there for me when I had my miscarriage this past June of 2019. Without him I do not know what I would do! Clarence is an fully indoor cat but recently has been flying out the door to go outside. I have caught him and put him back in the house but this time no one knew he was out. My fiancee and I found him hit in the road and took him straight to an emergency vets office. As of right now, my fiancee and I are currently looking for jobs and have no source of income. (We had been laid off about two months ago and have been looking ever since). Clarence needs Surgery right away and I need the funds to give him the medical attention he needs and to also make sure he has the proper after care. Clarence's injury's include two broken legs, internal organ damage, and a broken tail. I cannot lose my best friend! So please if you can donate I would be forced grateful. My fiancee and I are getting married in the next few months and really want our best friend to be well and able to attend. Clarence is more than just a cat to me, he is my baby and my best friend.
