In every category besides 100% you only do Goat Herding once having to herd 20 goats.
Besides being open to personal preferences and adjustments, two routes emerged over time. No matter which route you take remember to not press A at the start to prevent Link from talking to the farmer and not use A too often cause else the goats will chase you.
A good goat herding with this route will average between 19 and 24 seconds.
This route is a bit more likely to fail though but faster on average.
The movement in the beginning can vary, its safer to delay the first whip for a bit.
TAS goes immediately right instead, but its very risky to do that.
It is possible to get the cat's attention from over the river opposite the watermill, this causes the cat to teleport to you. Interesting to note, if you catch the 2nd fish once the cat has teleported the CS of the cat running to the shop is actually 10s shorter because there is less distance to travel. It should be known that it can seem very inconsistent on how to get the cat's attention
