Alienation of Affections, Feline Variety

Ever since I adminstered flea medication to my kitteh earlier this week, he's been shooting lasers at me with his eyes. It looks like this:

(Yes, it's possible I'm smelling my cat's head in this pic, it's also possible that you should mind your own cat-smelling business!)

Any advice on how I can get back in kitteh's circle of trust? He's always peowsed off when he gets tackled and medicated, but his ire is lasting longer than usual. I just want to get some cuddles, so I'd like to speed up this relationship recovery process.

Suggestions welcome.
