I've always owned a pair at a time, and they keep me hopping. Besides the time I spend directly with the pigs, there's also the time spent shopping/washing/prepping veggies, shopping and transporting aspen bedding, daily spot cleaning, floor time, weekly complete cleanings, weekly weighings and inspections, regular nail trims, occasional ivermectin rounds......hmmm, that's just what I can think of offhand. I buy hay and pellets online, so that saves some work. And I'm frequently down on my knees picking stray hay stalks and aspen shavings off the carpet; I can't help it. They're easily more work than a dog or cat (which I have also), but their sweet faces and high-pitched wheeks have captured my heart and turned me into their obedient slave. The aforementioned vet bills are a huge deciding factor in my limit of two pigs, as well. Kudos to all those here who have the time, energy, and resources for more, though!
