Help my cat survive!!!!

Hello everyone My lovely cat is in desperate need of surgery, which he will get THIS wednesday because something's stuck in his stomach which causes him to not be able to eat. He's lost a lot of weight in just a few weeks. He currently weighs 3.8 kg while he used to be a fat cat of 4.5 kg. We really can't afford this surgery right now, so of course we could use all the money we can get. Please help us by donating some, even the smallest amount helps. We don't want to lose our most beloved friend.
