I currently have an 18"L x 18"W x 60"H cage for my 5 month old quaker parrot. The photos illustrate the cage set up (threw one in there of my quaker also). I can't decide if I should buy a bigger cage. On weekdays, he comes out of his cage for about an hour in the morning, then he's in his cage from 8am until about 5pm while we're at work, then he comes out again for an hour or more in the afternoon/evening. On weekends he gets a bit more out of cage time usually, about 3 hours on Saturdays and another 3 hours on Sundays. He seems comfortable in his current cage and after being out for a while he doesn't resist going back in. So should I bother with getting something bigger or do you guys think this set up will suffice given his current routine? Feel free to share your cage sizes also. Thanks in advance for your input.
