I'm glad you are not getting your grandpa the cockatoo! And it is great you will be updating the love birds cages, they will certainly appreciate it!!! I shopped eBay it Amazon for mine. Maybe others have ideas for you.It is always better to invest into something of a good quality. I only feel stress when looking at a cage that is crowded. BTW, is it okay to use one of these ferret cages for my lovebirds? My grandpa told me that if I won't get him Cockatoo for his birthday next month, I might as well buy a new cage for the lovebirds at home. Also, have you ever made a purchase from Petstreetmall? Would you mind sharing to me your thoughts or might as well tell me where to find an extensive list of cages to choose from?
