I was thinking about a destroy or dismiss option yesterday, but this solution seems like an even better fit.
I had already suggested this prior, and i'm sure multiple people have as well. Unfortunately because Probeta has an option to remove all pets within your inventory they won't add an option to dismiss a pet like you can a cat.
