Help with Dobbys vet expenses

Hello, my name is Tessa and my baby boy Dobby has run into some unexpected medical issues regarding w blockage of some sort in his urinary tract. I had to take him to the emergency vet and I’m $550 deep into his emergency care. I’m currently unemployed due to disability and and struggling to pay bills and now my baby is sick. Please help us. Anything will help I’m so desperate to save my baby. 

UPDATE: they found debris in dobbys bladder and crystals in his urethra as well as bacteria. They wanted to hospitalize him but that would cost and additional $2000-$2500 and I cannot afford it. We are taking him him and getting him on antibiotics and wet food and observing him. Please please share this we need help! I don’t want to lose my baby.
