So I took a 9 month+ hiatus, and returned not long ago. I've just used a on one of my pets, but she (to be he!) hasn't changed ... Do these still work?! Or is there just some lag?

Did you select the "feed" or "use" option?

... Oh my god I am such an idiot. .____.;;; I was feeding, rather than using. xD Thank you!

It happens! No problem. 😄
