How exciting!!! Friday is almost here, and you'll be a mix of excited and a little nervous most likely as it approaches.
Your cage is fine, you do need some toys though. I love the color of your bedding (where did you get your bedding btw? Just curious?
You really don't need anything in the drop pan, I use bare pan and have no trouble cleaning it up quickly in the morning using paper towel, small dust pan to collect the pan yuck and then use a spray bottle of mix (2-1) water and vinegar, then wipe with a clean paper towel, takes only a minute or two pretty much.
If you prefer something in your pan, I recommend Custom Cage Liner
I have a coupe I use for my glider's roof-top playground (that's arranged on a spare drop pan & sits on top of cage). I have also had custom shelf liners made by her and they're awesome too. And, I have read many good things about them from those who have used them in drop pans. I just got such an easy routine with a bare pan, that I don't use them, but when I settle on my gliders vacation enclosure, I'll be getting some made for that.
I know many like using Glider Diners (or kitchens), I've used them, and then stopped. I set up feeding areas so that they have a little coverage, so either higher up in the cage and the lower one I typically use either a corner hammock or tuck them under a full bridge type hammock. I keep my whole cage covered from side-back-side, with only the front open, so my walls don't get messed up. With the exception of vacation set up at times, I have personally found no need for a Glider Diner.
For water, I love the silos, I switched from water bottles and haven't looked back (except on occasion when travel if it's all I can use at the time). Silos I use
in the smallest size, love them! I use for water, and have also used for nectar portion of their diet, but now use these Clean Cups
for their nectar. I like the cover over them to help keep clean, but I don't like these hanging high, unless sitting on a firm shelf for support. Cage mount or heavy bowls are suitable for the salad portions of the staple diet you use.
