Having watched our rocket kitten the past couple of days, he has reverted to the feline fiend we know and (mostly) love.
He sleeps like a proper cat, but not quite as much, and he responds to cat nap interruptions with more interest.
Like a true Spider Cat, he's been climbing more, including hopping up into a bookshelf we didn't know he could fit into. In more subtle way, one can see just by how he moves that his natural athleticism is back on display, with sharp defined movements be it walking, jumping, or just cleaning himself.
Unfortunately, his second night off drugs he celebrated by staying up and meowing at 3:30 AM, but he seems to be have burned off most of that excess energy now. He was quieter last night.
His brother seem does a little tired, and is not wanting to play with me as much. We think Billy has been chased around the house a few extra times by his now alert brother. :-)
