My right hand is the preferred location for jiggy-jiggy, as are the fingers & thumb. Phineas is under the impression that because he is attached to my right hand/fingers & thumb, that everyone else is interested too. This means he has to protect my hand from possible invaders.
Over time, he has become slightly less territorial over my fingers; he can regurgitate with someone sitting in the background without having to keep stopping to warn off that other presence. My hand, with the associated activity of the hand jive is a different matter though. When he is ‘in the mood’, he has to make sure no one comes within a certain radius of my hand. The more ‘in the mood’ he gets, the more protective & territorial he gets. Because of this tendency to aggression I usually engineer a hand jiggy-jiggy session in the cage. This has two benefits. The first is that he is more likely to finish ‘the job’ without having to keep stopping to warn off others. The second is that whoever shows an interest is less likely to be thumped.
Sometimes, when Phineas is extra-hyper, & slamming against the side of the cage to warn off would-be competition, I cover the cage over so he can concentrate on the deed.
Unfortunately, we now have an added complication in that Bezukhov has moved in with Phineas, albeit just being overnight stays. I dare not allow relations with my hand whilst Bezukhov is in the same, confined vicinity. This means that when Phineas wants to boogie-woogie, this either has to be done outside the cage, with Bezukhov locked in, or in the cage, with Bezukhov locked out! Usually Phineas wants rumpy-pumpy first thing in the morning after a long, jiggy-free night. Like I say… it is an added complication…
