Yes definitely get some pet rats!!
Me and my oh have 2 sisters, we adopted them at about 1 year old from pets at home.
In our first house, as I had just finished uni we were living with 6 other people (well OH lived with me when he was back from offshore) we let them have run of our room for a few hours and then back in the cage.
The house we live in now, they have the pantry room to themselves, houses to sleep in, ropes to climb and cage but free roam(which they love)
as others have said, you need a large cage and they will chew through everything they can. But I can honestly say, they are the most adorable, friendly, loving baby girls and they make my night.
One night Patsy stole a corn on the cob, ran to the end of the bed, jumped off (it was a low bed) and ran in to a cupboard to go eat it!
Unfortunately edwina is really unwell and we are going to have to get her put to sleep, but they have out lived the life expectancy, they’re about 4.5 now! Keep bawling my eyes out going in to see them both, but happy we have given them a great life and they have given us an amazing 4.5 years!
Get some! They honestly are so easy to look after and will bring so much joy to your life!
