I was always fighting over gp and rabbits because I wanted an animal who could live outside a cage aside from bedtime when they have to go back into their cage. A friend of mine had a bunny who lives outside the cage about 12 hours a day and was fully litter trained. The only issue was chewing stuff up but my rats do the same thing so I don't care. They chew up my stuff I get new stuff, anything that's toxic is kept from rat hands on high shelves they can't reach.
I figured rats wouldn't be able to play with them, my Bella more likely because she's a shy quiet rat who just likes to snuggle but her smaller sister Fili is a rough housing monster of pent up hyper activity and high prey drive. Trained her to hunt spiders in my bedroom and just about every other bug. I know rats and rabbits have gotten along,the same friend with a bunny has two male rats who play with the bunny and will even share carrots with each other.
I think regardless if my room mate gets a gp I might get one too just so they can live together and we could both technically have our own.
Can you get gp spayed and neutered? Which is more friendly with people girls or boys? Someone once told me girls were more likely to be snuggly with people and males are a bit more aggressive and likely to bit. How long do they live/ Ha sorry I am hitting you with a million questions just want to know about them since they seem eventually they will be living in the house.
