thanks and dont worry, as i said, ive done some research. but experience is what i lack.
i was also wondering, but forgot to put in the essay i wrote, is the furniture/decoration i have in there adiquate. Could i do with some more climbing areas, or is there anything i would be better having that dont have in there, etc.
ive managed to keep everything hide proof for the bugs. they are food after all, i want chuck to do a bit of hunting, but i found out they were all hiding in the skull where he couldnt get to them so i soon sorted that problem out by plugging all the holes in the skull.
