Rabbits smell wayyy more than guinea pigs. Well my most recent rabbit required a lot of attention (and I mean lots) compaired to how much I spend with my piggs. I give my piggs floor time and lap time daily. The rabbit needed floor time in a large pen, outdoor exercise (so he could eat grass etc ifdidn't give him outdoor time he would get mad), he needed to be held, and never wanted to spend time in his cage he always wanted to be out on kitchen floor. He wouldn't eat hay refused, didn't like his pellets. Cleaning the cage wasn't so bad, because he was litter box trained. But I had to clean those litter boxes twice a day otherwise he would start going in other places in his cage. And yes he was neutered but he was just a spoiled brat. He would actually chew on the grids to his cage when he wanted out. I have many other reasons why guinea pigs are easier to take care of but I don't feel like typing them right now. Over all for me my rabbit was a great pet and friend but he was overwhelming. I guess it varies for every one whether or not rabbits are more work. So loves2travel that is just my opinion.
