Nap, interrupted

I do not understand why Thomas even tries to nap in the living room when the parrots are out! Everyone had been playing nicely on their cages or had been in the kitchen with me (the greys).

Suddenly, Beeps decided to fly over by Thomas and hang out on his arm. Since Beeps is so light, this didn't bother Thomas at all. However, as soon as Rocky realized what was going on, the green-eyed monster came out. Even though he had been perfectly content playing in his cage, he ran over, climbed up the couch, and started threatening Beeps.
Beeps was pretty much oblivious to Rocky's threats and kept on playing with Thomas's sleeve. But he could no longer sleep since he had to supervise the parrots since they were so close to each other.
