Buying tips
- If you have a nervous or timid cat, an open-air design like the Petlibro Luma will get used far more reliably than an enclosed dome-style box.
- For multi-cat households, prioritize a model with cat identification (Litter-Robot 5 Pro) so you can track individual litter box habits and catch health issues early.
