From the publisher:
GM's Aid VI: Monster Knowledge Cards Volume 4—Animals & Vermin is the final release in the Monster Knowledge Cards line! Now, your Monster Knowledge Cards set can be complete!
With GM's Aid VI: Monster Knowledge Cards Volume 4—Animals & Vermin your job as GM just got easier. There is a card for each of the OGL animals and vermin in the SRD and each includes a number of facts about that particular creature. Each fact is tied to an increasingly higher Knowledge check DC. For Animals & Vermin, facts about real-world species have been included to add depth to these creatures. When the players characters are faced with a creature, whip out the appropriate card, have the players make rolls, and then consult the card to tell them what they know.
The cards have been formatted to print on any standard-size business card paper, or you can just print them on cardstock and cut them out using the lines as guides.
