We used a tent that they had never been in before. No toys.
I didn't think of doing the intros during the day. That would have probably helped.
We didn't try to push them today. We played with them separately. However, Jak got really aggressive towards my boyfriend. He Bit him until he drew blood...twice. I have read that after you introduce a male to a female their temperament changes, but I had never read about one becoming that aggressive.
Amelia acted the same as she always did.
