Yep, that looks pretty serious!

Sometimes Tubby sleeps so sound that not only will he not respond when I talk to him, he won't even budge when I touch him! And he always acknowledges my touch either by lifting his head, flipping his tail or making that little sound in his throat. That's when I like to get him to give him his daily pill. That way it's down his throat before he even knows what's going on. Then he just gives me this look like "What do you want?" and puts his head back down.

I forgot who said it earlier, but "silly kitty" explains soooo much.
