Thank you all so much for your pawsitive thoughts for Gus. He was slightly better on Saturday behavior-wise, so we didn't call the vet. He didn't really eat all weekend still (maybe a bit here and there) and he was still really mellow. This morning he greeted me like this:
rrgh--blogger is not uploading my video. i'll try again later.
I'm taking him to the vet today just to rule out anything major, but its nice to see him slowly getting back to normal.
(Edit: I took him to the vet, and she said his blood test results "were practically perfect in every way". They think he might have eaten something weird which caused him to act so strange. He is doing better today, which is great.)
I thought you would like to see some of the pics I took in a Gus and Waldo photoshoot the other day. My boys are so photogenic. :)
