newspaper, paper towels, nothing? My wife and I bought a pretty large cage for two parakeets, and one has since passed away - leaving the other with it. We've had them about 2 years, and removed the grid that prevented them from scavenging the very bottom of the cage for any fallen seeds. We read online that it could hurt their legs or talons could get caught if we left it in. Sometimes we'd catch them sniffing or picking at the bottom of the cage - and now I'm wondering if that contributed to the poor health of the one which passed? We read that parakeets were very picky of their eatings, so assumed they won't eat anything bad for them. Should we put back the grid that seperated the bottom of the cage from them? or is it better to put bird litter there without the grid - I see petsmart selling these huge pellets that act as litter, and are indigestible, so the birds won't be tempted by them. Any advice on what goes at the bottom? Thanks,
