My Walter has been diagnosed with FIP

I never in a million years thought that I would set up a go fund me account but I am struggling alot financially and I've been on disability since end of January.

My 7 months old rescue has been diagnosed with traces of FIP. He was admitted to ER since 4/29/2023 and is still in the hospital where they are monitoring him. I took him with these symptoms. Very dull fur, no food or drink for 2 days prior and he threw up yellow liquid so I rushed him to ER.

I've spent $1400 for them to keep him there and give him fluid and also run blood work but now they are asking for x-ray and ultrasound to get a proper diagnosis and I cannot keep up with paying the amount they are asking. Plus its the weekend and rates are even higher. I am losing hope and I am devastated. Walter does not have issues breathing nor swollen belly but he is depressed and keeps his head down and doesn't show interest to play with his fur siblings. He just wants to be left alone. Prior to this he was very playful and eating and drinking very well and super loving. This happened so quickly and having to pay this huge amount of money is making me lose hope. I am praying that Walter gets the help he needs during his journey. I miss him so much I just want him home where he can be with his other fur siblings and be comfortable. Please help
