I took Furface to the vet 2 days before he died.  She suggested
putting him to sleep ( she was crying when she suggested it), but I
just couldn't.  I brought him back home and put him on his little
pallet on the foot of my bed where he always slept. I positioned him
where he could see out the window, covered him with a blanket (my gf
insisted), gave him water with a syringe and gave him a lot of
caresses until the end.

He was 6 months old and feral when I "trapped" him inside my
apartment.  When I let him outside again, he was gone for 2 days but
came back.  And kept coming back foralmost 14-1/2 years.  I didn't
know it could hurt so much to lose a pet.  He is buried at the edge of
my patio, near the spot where he liked to sit in one of my chairs and
survey his domain.

Keep up the sub-Q's and any other meds the vet recommends.  The thing
about CRF is you never know if you have 6 months or 6 years.  I hope
you and Toma have many more happy years together.
