My cats don't like the dome and feel it is too claustrophobic. I have a half Main Coon rescue and it is almost too small for her, so I have to have a regular litter box with flush-able wheat litter. I also have an Abyssinian and I wish I could get her to use the dome because she uses both boxes and does high pole vaults (don't all Abys?) out of both litter boxes and sprays litter all over the carpet. If the dome was higher and had windows or was clear on the top or even all clear this might make a difference.
