Suggestion: Multiple purchases of each type of carers and automatic equipment after 7 days. Also a feature that allow players to disable currently occupied carers.
Reason: No one wants to forget to set reminder and let pets run away, I know there's another option to send pets to nursery, but it's a little bit time-consuming to re-equip their cosmetics and ui-relateds. About the second suggestion, I think because sometimes players purchase unwanted carers, a disabling feature can save that amount of credits for another 7-day period. Additionally, I, myself, want to disable them since they make my house look a bit messy.
