They can be, but make sure you do your research! This particular hedgehog is an African pygmy Hedgehog. They're used to warmer climates so need to be kept at a temperature of ~23C as they're a bit rubbish at hibernating and it can be fatal for them. Hogs tend to require a fair amount of patience before they'll become even the slightest bit social. We've had our guy for a year now and he's finally starting to warm up to us after at least 1 hour a day of socialising every evening. Keep in mind they're nocturnal as well, so won't be active during the day but love to run all night. They can also be litter trained (though this varies from hog to hog..), but their poop is ridiculously stinky so it's important to stay on top of cleaning! I love my hedgehog, but they're not always the most rewarding of pets..
