For a supervised play or exercise area, yes: it's dry, there's no mud or potentially toxic plants, and the rabbit can't dig a way out under the fence. As the flooring of an enclosure where it spends hours alone, no: rabbits and guinea pigs gnaw, and swallowing synthetic fibre can cause an intestinal blockage. If you see it pulling at the fibre, remove it from that area.

Yes, in covered terraces, porches, play areas or shop windows. Indoors it gets no sun, so UV degradation stops being an issue and it lasts much longer. It's worth choosing a low pile height, 20 to 25 mm, which is easier to vacuum and maintain.

Yes, more than natural grass: in high summer and in direct sun, a dark-coloured grass can go above 55°C in surface temperature. Olive-toned shades and cooling-fibre technology narrow the gap. A quick hose-down brings the temperature straight down, and a shade sail solves the problem on very exposed terraces.

Yes. These parasites need damp and organic matter to complete their life cycle, and artificial grass doesn't provide that. It's not an absolute barrier — your pet can still bring them in from elsewhere — but it removes the breeding ground in your own garden.
