trying to maybe theorize here! :
1. maybe he touched a box or something and then killed his uncle’s dog or poisoned him by mistake or something or maybe the vital that cause him to be human animal hybrid
2. trauma from either killing his uncle’s dog (assuming his brain went ptsd mode and he forgot everything about it) or he had to take therapy to stop his animal hybrid traits from happening
7. in my opinion it might be pig because he is mysterious plus by the way Dr. G is acting and the others i feel like he is shady so maybe he’s the one who sent it..

Reread this and other than the gooning the story itself is actually so mysterious like what is going on
1) Little A got in big trouble as a kid and wasn’t allowed to visit Uncle A or the farm anymore, but all he did was open a box/ chest or smth?
2) Lil A was homeschooled and sheltered after that incident, also failed at multiple jobs from feeling like he didn’t fit in/ others felt smth off ab him
4) The farm is unknown
5) Who tf are the mysterious organizations hauling these half animal ppl up, bc the general public seem to have no clue ab this
6) Uncle was going at it with Fluffy the dog
7) Uncle DID NOT send the initial letter to little A, and Unc is on his way back to the farm rn tho it’s been a while alr so maybe smth happened to him
8) Black hair doc? Yeah that guy was getting ate out by some freaky creature
9) Piggy got some kind of ED
