Why are my kitty coins going down?

I didn't know it was possible I would like to know the answer

it can go down?

Wait, how many did you lose? Never knew that was a thing?

Its a bug. Has happened to me many times. Have written to the PH team regarding this and apparently there's no fix. You just need to wait a couple of days and sometimes it resets to the right number and other times you just end up losing it :/
