No, the can itself looked fine, nothing out of the ordinary. Just inside, both of us thought it looked less "moist" than normal. Maybe a slight discoloration too.
I'm just afraid if that's what caused it I'll get another batch that's bad and not know it till he's at the doctor again.
The Clavamox, an antibiodic helped, as well as the IV they had him on. So he's doing a lot better, I'm just can-shy!
