Pet Food Guide

When looking to spend your precious Gold on pet food, you want the most efficient pet food possible. So, we need to find what is the most efficient at each pet rank, since the cost of feeding pets increases with each rank. The most efficient food in a particular ratio is, therefore, the most powerful and expensive since the ratios lower much more slowly.

While going through every shop item would take a long time (aka require a spreadsheet), let’s take a look at 3 items:
10x: Soft Drink (150/15)
6.5x: Chocolate Cream Sandwich Cookie (1300/200)
5x: Ambrosia (5000/1000)

Soft Drink:
Ah yes. An absurdly high FP/Gold ratio, and so cheap too! Or is it? People sometimes forget to factor in the cost of feeding.

Pet Rank Item cost + Feed Cost Adjusted Ratio (FP/Total)
Common 15 + 5 150 / 20 (7.5x)
Uncommon 15 + 10 150 / 25 (6x)
Rare 15 + 30 150 / 45 (3.33x)
Legendary 15 + 60 150 / 75 (2x)
Divine 15 + 150 150 / 165 (0.91x)

Soft Drinks are pretty effective for Common pets… and quickly drops off after.

Chocolate Cream Sandwich Cookie:
The next candidate for an efficient food item is the Oreo! No, not that one. Let’s see where this food item works.

Pet Rank Item cost + Feed Cost Adjusted Ratio (FP/Total)
Common 200 + 5 1300 / 205 (6.34x)
Uncommon 200 + 10 1300 / 260 (6.19x)
Rare 200 + 30 1300 / 240 (5.42x)
Legendary 200 + 60 1300 / 260 (5x)
Divine 200 + 150 1300 / 350 (3.71x)

The Cookie maintains its high feed ratio through even Legendary, being stronger than even base-level Ambrosia. Even with a Divine Pet, having enough fame would actually make Cookies more effective than the bigger Ambrosia.

Ambrosia:
With a whopping 5000 feed power and 5x base ratio, it is efficient at all levels and maintains efficiency well. Ambrosia was, for a long time, the largest FP item, and is still a good item.

Pet Rank Item cost + Feed Cost Adjusted Ratio (FP/Total)
Common 1000 + 5 5000 / 1005 (4.98x)
Uncommon 1000 + 10 5000 / 1010 (4.95x)
Rare 1000 + 30 5000 / 1030 (4.85x)
Legendary 1000 + 60 5000 / 1060 (4.72x)
Divine 1000 + 150 5000 / 1150 (4.35x)

As you see, cookies are more efficient until Divine, but bigger foods are ever more effective as your pet levels up.
