Everyone always daydreams about having a starter or a shouldermon, but realistically how difficult would it be to keep one of these things around your house?..

And just to clarify: by "realistic" I don't mean actually existing IRL and being chained to real life physics. I mean how would you keep it fed? How much space do you need to make for them around the house? Do you have to teach them to hide their powers or can you make use of it outside of battling?

Yeah, I know, but what after that?
