[cypher]

Robos do generally tend to be harder to tame than Russians & less interactive but like all species they vary a lot & some do become very tame & easy to handle, they would require a fair bit of patience to get there though & if you had a pair much less likely to want to interact than one living alone.
I would have a good browse through the threads in this section & read other people's experiences & stories about their robos to get a better idea of the kind of pet they make.
As has been said you will need to have four cages if you get another pair, it may seem unlikely when they're being cute & cuddly together but you do need to be prepared as they may well fall out as they mature.
