Sorry all, I promised an update last night, but I was too tired and fell asleep on the couch beside Miko's cage. He had a good night. Took his meds last night and again this morning and ate heartily his chicken soup. Sebastian was delighted to have his buddy back home, they snuggled all night. I reviewed the xrays with the vet yesterday. Miko is completely full of fluid, even his lungs are floating. Hopefully the meds will rid his body of some of this fluid. The vet still suspects an enlarged heart, but doesn't know the cause. I will take Miko back to the vet next Thursday for another check up and more xrays to see if the meds are doing anything for him. I gave him a big hug last night from all the people that were thinking of him. Thank you everyone, you don't know how much it means to me.
