My buddy may be dying

Lol, funny "Wally" agreed with you.
Like I said before, you got lucky. As much as your actions may have been noble, you took Zeus from a neglected environment and brought him to a hostile environment.
As much as you dont want to be judged, you open yourself up for criticism posting anything on the internet.
I hope you get Zeus to a vet, wishing the best for Zeus.
