Please help to pay for my cats vet

Hi my name is rose and i have 13 cats,1 dog and 2 birds. We saved these animals and we dont have enough money to support all of them. 3 of my cats are prone to urinary infections and last october one of them went for surgery because of how serious his blockage was,we still havent paid those fees off completely... My cat,Lex is now suffering from a urinary infection which is preventing him from urinating.He does not look like he can make it much longer.He has been sitting in the same position for hours and screams and struggles in pain when he moves.We also have another cat -Buggs ,who has severe asthma but we are unable to take him to the vet as the costs are sky high,he suffers everyday and coughs all day long. We also have had many cats and other animals who have passed on ,who we tried to save so hard but unfortunately vet bills were too high and we could not help much. We try very hard to keep them in good health,we feed them pumpkin every week, we buy special chunks to help ease their urination,we give almost all the cats water in a syringe every few hours to ensure that they are urinating ,yet somehow they still get sick and we are left to watch them suffer helplessly. Please help us to save our animals.
