>>311570You're absolutely right if you keep them in there 24/7 and its a small cage for the species you're keeping.
That being said, provided you DO open the cage and have them be free to roam your home, it isn't any more inhumane than keeping a housecat. At least with tiny species like budgies, parrotlets, canaries imo.
I still think confining something big like a cockatoo isn't very nice but as long as they're well cared for, it's none of my business.
