Tortoises and hedgehogs are unlikely to live together comfortably. Tortoises are generally solitary creatures. Hedgehogs are more social, but they could be at risk from the salmonella that many tortoises carry. Overall, the environments that these two animals require are quite different so it’s a real challenge for a tortoise and a hedgehog to live together.
Tortoises shouldn’t roam around the house. They could get injured, lost, too cold or too hot, fall or get stuck and be attacked. A tortoise roaming around the house might also spread disease. Even when supervised around your home, you will often have to handle the tortoise (pick her up) to put her back safely within a supervised area. This can be stressful to your tort.
If a tortoise vomits, you must try to find a cause of the vomit and remove it. Vomiting is not common in tortoises and can be serious. If this behavior persists after changes to diet and living conditions, take your tortoise to a veterinarian. It might help to collect some vomit in a small container in case the vet decides to test it.
Tortoises do tend to like the rain! Some species are more acclimated to it than others, given that they are native to tropical rainforests, but all can have a bit of fun in the rain! In the wild, tortoises are outdoor animals so exposing them to safe amounts of rain will replicate many of their natural habitats.
