Help Put My Baby To Rest

My sweet baby (Pumpernickel) who I’ve had since my other cat gave birth to her 16years ago, isn’t doing well at all. She unfortunately has cancer with multiple tumors on her chest and stomach. One specific tumor is constantly growing and is now an open wound. It’s oozing, pussing, has an awful strong order and is just very infected at this point. She’s very uncomfortable and very weak. She can barely walk and can’t even lay down comfortably anymore. I called multiple places even the human society and some places won’t take me and human society isn’t answering my calls and the places that will take me are just so expensive. I really don’t know what to do or where to turn at this point, I just want to put her to rest, she doesn’t deserve to suffer like this and it’s very tight for me financially. As I understand and know times are very tough for many and a lot of people financially are strapped as well. I thought I take a chance on this platform and see if anyone is able to help me. I truly would not be asking and doing this if I wasn’t truly stuck and this is my last resort. It’s breaking my heart everyday and the last thing I want to do is say goodbye to one of my babies but this has to be done sooner then later. If anyone is willing and able to help I appreciate any little thing from the bottom of my heart. And I thank anyone who is able to lend a helping hand. Our animals are our babies our family and we do everything and anything for the ones we love. Thank you all for taking the time to read and hear my situation. I hope I can end my babies suffering I just need a little help.❤️‍
