Is it OK for my atiel to eat the x-m tree needles?

i don't believe the needles are toxic but you want to be careful he doesn't get one stuck in his throat. since they are so fine and he doesn't have teeth to completely break it up there is a chance it can get caught on the way down. he also may be looking for something new to munch on. try giving him dif treats or do a small change in what you feed him. hope it helps
