My retics are sweet as can be however they are EXTREMELY flighty they do not like to stay still. I think retics are harder to work with just because its hard to get them to go where you want them to go because they want to explorer every little tight space you ahve in your house and my god dont ever let one get under your couch! Thats a pain in the butt. BUt yea oskar, trixie, and kate are all great.
