Is there any way that I can increase the odds of my pet getting a job, or is it total luck?

Also- what type of potion/other thing do I need in order to make my Montre all nightmarish? (:

Thank you for the help!

for the pet.

Also, read your pet books to increase its intelligence! That'll get them a job.

Thank you- love the chinchilla, and if you are THE Doctor, where's your bowtie? (:
