Hedgehogs kept in homes with various pets could hold their own against the other pets since they have defense mechanisms. But the hedgehog’s safety could also be dependent on the characteristics and temperaments of those other pets. Always be around to supervise interactions between these various household pets and your hedgehog.
In general, hedgehogs seem to tolerate other pets well. Pet cats learn quickly that keeping their distance away from your hedgehog’s quills is a good idea. A lot of dogs also have awareness of this defense mechanism and think twice about approaching. But then there are also large dogs with strong prey drives that might play roughly with a hedgehog even with their quills and then injure the small animal.
Initially, a ferret might try and get at your hedgehog, but it will soon learn to respect the smaller pet’s quills. Because these encounters with your other pets could stress out your hedgehog, be on the lookout for stress indicators. Some of these indicators are pooping or peeing because of fear. If this happens, limit your other pets’ interactions with your hedgehog.
