I just want to keep my cats

Hello.. I hate to have to do this but I took in a kitten over the past month and I am asking for help. I love him so much and giving him away is just not an option. His name is Niko and he is a male and he has a brother named Koby. They are very bonded. I have talked to an after hours emergency vet and Niko needed to be seen, which was the date, 09/21/2020. Exams are 50 dollars; 100 dollars together for both kitties to be seen. Niko also needed antibiotics, as well as other things that were announced to me with the results of the exam. He needs shots up to date and I still need to get him neutered because his right testicle is swollen and that’s why he needs to be neutered as quickly as possible. For all of this by itself, I am asking a minimum of 400.00 but not even sure if that will cover things. I can provide receipts for the vet bills or whatever you ask. Koby needs to get his rabies shot as well. I just don’t know what to do . Niko is the white cat and Koby is the Tuxedo. I’m not expecting anything and we’re all in this together. I appreciate even the smallest donation.. And I know it sounds kind of silly to say but my cats are my best friends. I also live on my own and am struggling with bills and need to be able to continue caring for my cats. They support me emotionally and I just could not do it without them. Bills have been so hard these past few months. When I first got Koby, I had to spend quite a bit of money because he had some bad stomach issues and wasn’t even using the bathroom normally. Times are hard.. Thank you for reading. Share this if you can! ): Update : They have another vet visit and I am literally in debt . Anything helps..
