Jack gets up around 19.30/20.00 and Clive earlier than that.
By the time i go to bed Jack would have had about two hours of freeroaming.
He used to be happy with one or two freeroaming sessions but now he's not and wants out again. When he doesn't get what he wants he throws a tantrum!
His temperament has changed and i haven't been able to figure out the reason behind it.
Rory went through something similar but more extreme. I figured out the cause, did something about it and he eventually calmed down again, took weeks though.
The reason for Rory's emotional dilemma was caused by my ignorance. I had taken in a rescue female Syrian, the beautiful Dolores and let her freeroam. Her squeaks of delight weren't squeaks of happiness, they were mating calls! Rory was a handsome male Syrian in his prime who was driven insane by the scent of a woman.
This household has been all male aside from myself for a long time until i took in Lilly recently. Lilly is a female dwarf so i wouldn't expect a male Syrian to react to her romantically.
I sat with Clive by Lilly's cage so he could see, sense and sniff her which seems to have reassured him. I'll do the same with Jack as soon as the opportunity presents itself.
