A few questions about gameplay

[Avatre]

Hi, I've been playing this for a couple of days now and have a few questions I can't seem to find the answer to.
Pet level: Is this a temporary thing or do they actually have continuous levels? If so, can they be seen anywhere?
Fences: Purely cosmetic, or do some of them have better durability? (the wolves bash straight through the ones I had in that horrid dream I totally suck at)
Electric Motor: Can that be found somewhere before repairing bridges with nails?
The hay bales put in the barn, are they used by grandparents to feed the animals, or stolen by those annoying deer?

Thanks :)

PETS: The dog and the cat's levels go up by plating with them. The dog is pretty straight forward, but the mechanics on the cat's play is janky at best. FENCES: I think that the wolves are poorly thought out to be able to break through whatever is in their way (hopefully the large number of people who hate the whole wolf mechanic will get the dev to re-think how they work). ELECTRIC MOTOR: There is a quest to get the merchant to like you that cuts the motor's cost - however it only cuts it to 15k. There is a motor in the game but it is in a derilect house being one of the bridges . HAY: The hay bales are the way to feed your farm animals; you can use loose hay later to feed some wild animals.

Pet levels are temporary - you have to retrain them every so often. You can see their level above their head. Once the color starts to drop, play/train them a bit to recover the full amount.
