Rats are so gentle natured, and enjoy human company, they live longer than wild rats and as long as they have another rat companion and a good owner who has time to devote at least a few hours of play a day, you will get to spend around 2-3 years with an animal will be happy and enjoy your company and the life you give it.
They are very intelligent, the 2nd most intelligent rodent (squirrels are 1st), they are extremely social, if you get a boy they tend to be less active so will stay on you for longer but female rats prefer to come up to you and play with you, climb all over you, go in and out of your clothes, kiss you and try to play games with you. Some rats will sleep on you and you can carry them around the house and outside. When I was little I use to take my rats into school with me in the morning haha.
The only annoying thing about rats are they love to chew things so you have to rat proof your room.
I love my rats so much! They make amazing pets!
I hope this helps x
