I was worried about Butter last night because I went to feed him some crickets and he refused them. No interest whatsoever.
Then i remembered I put a whole lot of meal worms in his bowl earlier. It usually takes him several hours to find new worms in his dish and I hadn’t seen him out since then so I figured they were still there.
Two left, out of at least 15 (I was out yesterday so I gave him a few extra). They weren’t the biggest worms I had ever seen, but that explains pretty clearly why he wasn’t hungry.
