24. Prairie Dog
The prairie dog is a burrowing rodent from the grasslands of North America that could cost $500 to $1,200. It needs space where it can burrow and forage for food, and they have to socialize with others of their kind to be happy.
These rodents will chew through anything to file down their incisors, and they will graze day and night, so owners have to buy grass and seeds to satisfy them.
Fresh water must be available to them at all times, and they should be fed fresh greens such as parsley, cilantro, carrot tops.
