I am not really sure. I have two cages both of them given to me by the people who had my gliders first. The cage she is in in the picture was given to me by someone far more knowledgeable to me in gliders and she said the metal type was ok for them. its not like chicken wire if thats what you mean.
also - my vet said to keep them separate for 7 days so she doesnt open up his cut, but people on here have said they put them back the same day. i have the two cages on top of each other so they can talk and they don't seem frazzled at all from being away from each other (previous to my owning them they were both lone gliders so they are probably used to this) - any thoughts though on whether its ok for them to be apart so long while she is pregnant?
