Well, now that I've had my buns for a couple of months, I realize my current system is flawed and I want it better. So, I've been brainstorming. I want a system design that is comfortable, efficient, and easy to use. One of my current cages opens inwards, at first I loved it, now I hate it. So I want doors that swing out. The wooden rack that holds my cages now, collects food, poo, and hay in the cage, that has to cage. I would like stacked cages, 3 high. Don't care for the 4 high, I don't want to have to stand on a stepladder to deal with the top row. After seeing some of chinbunnies cages, I believe I will make my cages. I have a feedstore I pass that has literally all kinds of wire you could want and for very reasonable prices. I would like an automatic watering system, this dunking water bottles into a 5 gallon bucket is for the birds. I am familiar with working with tubing, I have an auto-waterer for my caged birds. I just can't seem to find the nozzles for an auto watering system for rabbits. Anyone want to point me in the right direction? Another question. I have seen stacked cages with and without drop pans. What's the info on this? Since I run worm bins, it'd be nice to have all the poo land underneath and I can shovel it from there, into the worm bins. I figured if it was that easy then everyone would ditch the drop pans and opt for stacked cages that allowed the poo to drop all the way through. Then I got to thinking about it, and while rabbit poo is quite tolerable and not exactly all that messy, their urine is a whole other story. A third point of discussion. Urine guards. I've heard many different opinions on these. I thought it'd just be easier to cover my wooden walls with plastic sheeting or some other easily washed material(plexiglass, etc). Any suggestions? Feeders, I plan on just large metal J feeders. We had a couple of medium ones now and a large. Definately in favor of the larger! Hay, I just pin in the door or put in the cage completely. I've seen the hay racks, but they just seem like a waste of money(IMO!). I'd rather spend my money elsewhere, am I right? Extracurricular.. Hehe.. While I know rabbits do well in cages, I can't help but feel for their boredom. Any good "toy" suggestions? I currently let them in an outdoor pen under immediate supervision, but I only have so much time I can sit by the bunny pen and watch them. They only get to go out every few days, I'd like to get them something to play with in the cage. If I remember one of the many things rolling around in my head, I'll add it later.
