My doves like this type of toy with the bells on the bottom. It's a parakeet toy. Their cage is a tall cat playpen that I got about 15 years ago for $99. They also like to sit on shelves. I use painters tape to tape newspaper over the shelves because they seem to like the solid shelves and it's very easy to clean that way. I tape the paper underneath the shelf part so they can't pick at it. I hung small rope, sisal, and shredded paper toys from the ceiling of the cage above and to one side of the shelves because they seem to like having a "curtain" to sit by when they're on the shelves. You can see one in the upper left of the picture.
On the right side of the picture, you can see a stainless steel bowl. That's a medium-sized bowl for dog crates, and I put shredded paper in it. The female always sleeps in there. Sometimes, the male will sit in there with her, too.
I use newspaper on the bottom and unscented paper pellets that I scoop with a cat litter scoop every day. That's only because the big poops on the bottom were gross. The birds like to peck around on the bottom of the cage, so I think it's a little cleaner for them.
For their dishes, I got medium-size hooded bird dishes so the seeds stay in the dish when they poke around for food. Don't get really deep dishes, because a dove can stick its head really far down and then get stuck. This actually happened to one of my doves, so I use hooded dishes that are about 2 inches deep.
I make my own seed combination from seed I buy online because I didn't like the commercially available dove food in the pet stores. The company is Island Treat, if you're in the US. I use Nature's Garden small, and Fruit and Nut medium and small. I also shred carrots and dice an apple slice very small and give that to them with defrosted peas. Sometimes, I shred broccoli tops and give them that, too.
You can't house two males together because they will fight. It doesn't matter if they're from the same family or not. Two females are better, or a male and female pair. They'll mate, but I discard the eggs. If you don't, you'll have dozens of doves in a couple years. A pair of females will also lay eggs, but they're infertile and you have to discard them, too, as Marina said.
I got my doves as adults and have had them for 16 years. I hope this info is helpful to you.
