First off, I'm gonna point out similar threads such as [Engineering] All pets and companions, a guide and Making money with non combat pets.
Here's how this guide is different from the others. For me the hardest part during crafting process has always been finding out which materials I need, how many of them are required and where to get em. It gets pretty confusing if you plan crafting 50+ pets at once. To make matters even worse, some materials for engineering pets require leatherworking and jewelcrafting parts. To make things as simple as possible, I decided to create a quick excel sheet to sum up all the required materials needed for the work, whatever combination of the 5 non combat pets you want to craft.
The sheet includes the creation of following pets:
Mechanical Squirrel
Pet Bombling
Lil' Smoky
Tranquil Mechanical Yeti
Lifelike Mechanical Toad
Check out the sheet yourself and please provide feedback whether it was useful to you or not. The sheet MAY contain some false information, but I'm pretty sure it's correct. There are also 2 different versions, one for the old excel and one for 2007+.
