SOLVED. Dystopian Teen book about red eye disease and runaway boy with animals. [s]

[Anika]

Dystopian fiction book about a disease that makes your eyes red/pinkish. Towns are evacuated into these industrial living quarters. A teen/preteen boy runs away from one of this 'quarters' with a bunch of animals (i think like a horse or cow and some other smaller ones). I cant remember where he is going but he comes across these berries and hes starving so he eats them and his eyes turn pink so he freaks out and thinks hes infected and passes out. He wakes up to find hes in a foreign house being treated by this teen girl who has a cat. The girl says the disease is fake i think or at least doesnt affect animals and something to do with a corrupt government. And he wasnt infected he just ate poisonous berries. Then the gov shows up i think to take the cat??
I read the book in about 2013-14 and i think it was a young adult or preteen book. I read it in britain and cant remember any other details.
