Compassion for Mellow: Euthanasia and Cremation

hello all, I really wish I didn’t have to do this but unfortunately my best friend of 17 years is dying . My cat mellow has been in my family since I was just 6 years old and has been an extremely big part of our lives ever since . In his old age I find that he is suffering a great deal being that he’s had 3 seizures already in less than 24 hours . The best thing to do unfortunately would be to put him to rest and out of the pain he is suffering from . I am a stay at home mom of a 6 month old and can not afford the expenses to put my sweet boy to rest the proper way he deserves. Ultimately 500 dollars would be the expense for him to be euthanized and cremated … anything helps . Thank you in advance :(
