I actually also know of someone who does live in the city and has a pet pig! She walks her pig on a leash and she(meaning the pig in this case) is about the size of a dog but a lot wider/heavier than the average dog. I don't know the owner personally so have no idea if the pig is difficult to take care of but they seem like a happy pair when I see them walk outside. When people get a pet piglet they definitely shouldn't underestimate taking care of the pig when it grows up though that's for sure.

Keeping chickens doesnt require a huuge farm plot, so I do know a few people who have some chickens for fresh eggs & companionship in their garden without having a whole farm. You wouldn't be able to keep them in the city without a garden though so I personally dont know that many people who have chickens as pets. I think the OP of this gif specifically posts a lot of videos of pet chickens/pigs, probably they are one of those people who have the space for it themselves.

This sounds like a hot take your uncle made up to make his cheating seem ok "I only started cheating after she accused me of it!". Even if it's true it still doesn't excuse cheating instead of just breaking up.
