Question: How to increase pet counts

[Bigfire]

I have a lot of duplicate pets for breed purpose. I regularly run into situation where I have to trim the duplicate. I know there's a way to increase the pet count, but I couldn't find out how. So how do I up the overall count?

There's an item now called Pocket Pet Portal which will allow up to 1500 pets.

Pocket Pet Portal is a reward from Battle on the Broken Isles
