After a morning run, Thomas was drinking Gatorade and Brian was running around the table. He ran over to the glass and started tapping against it, which we took to be an indication that he wanted to see what was inside.
Thomas obliged him, tilting the glass down, expecting Brian to run away, but instead Brian ran into the glass!
Thomas then dumped the Gatorade and filled the glass with water to see if this would continue. It did!
I know I am a broken record on this, but how did his former owners give him up? Since they didn't ever let him out of his cage, perhaps they had no idea of what they really had. I can't believe how lucky we are to have him.
