Update
Quick update on Squish. I could use some advice.
He recovered from his pneumonia, had his teeth trimmed but still wouldn't eat on his own. Vet hospitalized him for 4 days to observe him, do blood work and feed every 2 hours. His weight finally plateaued with a 92 gram weight loss in a month(down to 580grams).He's back home on a appetite stimulant and did another week of antibiotics (ugh). He's off all meds now. He's down to about 571 grams and still won't eat on his own. Besides this, he doesn't seem "sick". He's not quite as active as he usually is, but he does play in his playpen everyday, fur is shiny.
