I'm not saying that I like the idea of acrylic (or plexiglass) cages, but this is not a new idea. There are plenty of them out on the market. Including full enclosures with air openings only on the top.
I think that, instead of being rude to KL31, we should help to make this the best parrot environment as it can be given the situation.
I think that, by attacking KL31, you will just drive him/her off and he/she will do this anyway, but without any help from those that can improve the bird's situation.
Do our birds get exercise from climbing on the walls and ceilings of the cages? Of course. Will KL31's bird have that? No. So, make suggestions to give his/her bird activities! 4' x 4' x 8' can hold a lot of perches and nets and toys and activities.
Let's offer ideas that will keep KL31's bird active and entertained so the bird can be in the middle of the activity in the house.
KL31 seems willing to clean daily, Luvparrots, but not PERMITTED to have the mess get on the carpet at all.
Yes, Dave, these things should've been considered before getting the parrot. That is water under the bridge. You don't know if KL31 and his/her parrot are well bonded and loving. This may be a temporary thing until KL31 moves out from his/her parents' home. (Unfortunately, KL31 hasn't really given us any personal information or pictures of the parrot or himself/herself so we can get personally invested...)
KL31 did say that he/she would be taking the grey out. It would be good to know what he/she means by that - other playstands and/or perches? Time on the couch?
