you are the "entire keeper" when you can provide a single bp with everything it needs to live a happy, healthy life and love to do so. breeding them is a bonus but not necessary. if you dont love them you shouldnt breed them whether you have one or one hundred pairs. i think new keepers who breed too soon may be excited but not in love. its exciting to think of all the future breeding possibilities but to get there it takes more effort than expected and to get there youll find out that you have to be in love.(or crazy...)
