I would think it's comon sence, three is more, so, yeah taking care of three rats would be harder. For one, they make more of a mess, and you'd have to clean up after them even more frequently, than with just your two rats.
well, i have a pet rabbit and a pet rat and the rabbit is alot harder! the rat doesn't need too much attention. the rabbit needs to get played with everyday and needs to be cleaned every 2 days.
Hairless rats live as long as normal rats do; 2-3 years with proper care.
If you are talking about domestic rats, about 2-3 years, depending on how well you take care of it. Mine is pushing a year and a half.
Pet rats usually live to be about 4 years old.
Domestic rats typically live 2-3 years. Wild rats have a shorter lifespan, usually 1-2 years.
Anywhere between 2 - 3 weeks
Rats can live anywhere from 2 to 3 years. I've even heard of them living as long as 5. It depends, like with most pets, how well you take care of them. Also breeding is a huge factor.
2 rats
