I have to agree with tess and cetan...looks like 2 girls to me too..pretty girls at that
Love the cage. PERFECT size.
Want a little tip? If you get plastic flexible cutting boards and cut them to fit the bottom, over the grate, it makes for easy cleaning. Much easier than scraping poos off the grate, AND it gives them a flat surface to walk on which is good for their feet. They get tired of having to wrap their toes around perches and cage bars all the time.
I'd say line with paper towels...but having girls there that could lead to breeding mode being as they could shred the paper for "nesting material". Try to avoid shreddy type things with females.
Great to hear they get along so well. Not always the case, especially with females and sometimes with the males also. You lucked out
Know that that could change as they mature, one or the other, or both could develop territorial issues, or become a bully. If that happens you will have to separate them. Hopefully they will continue to get along just fine tho...just be on the look out for changes in behavior/attitude.
