There are a number of wild pets which are seasonal, weather or time-dependant, so if you’re looking to add them all to your collection, this should help.

These are all the ones listed under the Pet Journal which specify the conditions needed to spawn.

Arctic Fox Kit

The Storm Peaks – snowing

Baby Ape

Jaguero Isle, The Cape of Stranglethorn – raining

Qiraji Guardling

The Scarab Wall and The Scarab Dais, Silithus – Summer

After capturing one on the beta, I was excited about finally adding one of these to my collection as it’s the last one many of us need for our Kalimdor Safari achievements. Many speculated that the pet would start appearing after Mar 20 – the end of Winter (for fishing up a Winter Squid) but it seemed odd that Summer would come straight after Winter.

In response to my tweet this morning (21 Mar 2013), Mumper confirmed that the Qiraji Guardling will not appear in-game for another few months.

This goes to show that the Summer Bass and Winter Squid follow different seasons to the pets.
