Hi Lolly,
It’s great that you’re doing research on cages! If you go to the habitat section, you’ll be able to see some ideas of what other people use, it’s probably a good place to start!
The first thing you need to decide is inside or outside. As this is a house rabbit forum, most people here are pretty pro inside rabbits. It’s so nice to be able to interact with them and feel like they’re a real part of the family inside.
The ones you’ve linked to look too small though, it’s really important for bunnies to have lots of space to run around in.They also need time out of their cages every day.
The other key point is that the floor must not be wire, as that can be very damaging for bunny feet.
Personally, I have an indoor wooden and perspex pen that my dad for me, it’s similar to this, and they also get lots of time out of it:

Anyway, those are just a few thoughts that you might like to consider.
