With how long hoards can get, it would be REALLY nice to have a "cancel hoard" button. I have a pet I've been wanting to evolve, and I had to wait a while for her to recover from her hoard. When she finally recovered, I went to her page, and, out of habit, immediately clicked on the "send on hoard" button. I now have to wait two days for her to return and recover so I can evolve her, and even then I'm afraid I'll just wind up accidentally sending her on a hoard again out of habit without evolving her.

I know others have run into this problem too, be it because they wanted to evolve their pet or they wanted to apply a potion to it before sending it out on a hoard.

Even if there were only a short window of time for the button to be available (like say, 1-5 minutes after you send the pet out), it would be extremely helpful. Though if the option were constantly available, there should also probably be a confirmation screen, so someone doesn't accidentally cancel a pet's hoard when they're five minutes from returning!
