Griffin jelousy, Show boss the unicorn?

I was at my office at work the other day whalst walking my pet griffin and i saw a unicorn in the cupbourd, everyday i go to visit him and feed him chicken biriani (he loves chicken biriani, but i have to use quarn chicken because he is a vegetarian) and custard tarts, but i have to sneak them from my coluiges desk. I go to see the unicorn everyday, we play ping pong in the canteen together, but my Griffin doesnt like ping pong as his wings get in the way, I make sure that i pay the griffin equal attention to the unicorn but i think (although he wont admit it) Griffin is jelous of unicorn, how can i get griffin not to be as jelous? and, do you think i should show my boss the unicorn, because the cleaner thinks its me pooping in the broom cupbourd.
