You should follow the introduction procedure first.
it is available on several websites including this one.
(at work, don't time to look it up, but I posted 3 sites available
on a post just a few weeks ago.)
pls do a web search. several items are important for introductions, swapping
pouch, neutral territory introduction, neutral new cage.
We do everything in 4 to 6 weeks.
2 weeks pouch, scent training, 2 weeks cage close together and continue scent training.
gliders a territorial and will fight badly if not properly scent trained.
