Plus there is an upside to the bigger cages: MUCH easier maintenance! My Quaker Sammy came with a cage similar to the one you use, with the plastic bottom attached to bars. I use it as his sleeping cage and travel cage when we go to the lake, but it is a PAIN to clean. I bought him
a slightly smaller version of this cage (just not as tall) and it is SO much easier to clean. It is metal all around so poop can't get stuck like it does with those small cages that have plastic at the bottom. Also bigger cage to bird ratio=cleaner looking environment. After one night Sammy has pooped his sleeping cage up like crazy and it looks NASTY, but his day cage is SO big compared to him that it looks really clean even when it's dirty because there's just more area to NOT poop in. So beyond it being better for the bird, it has some REALLY great ups for YOU, and like my Quaker, your lorikeet could get away with a cage meant for birds with small beaks (like finches and budgies), which makes them a lot cheaper than the parrot cages you need for birds with giant beaks, whatever their body size is.
