I took in a stray and her newborn kittens. the kittens, at about 6 weeks old, got very sick. with a respiratory infection and eye infection. They were taken and fostered for about a month. The foster did not want to return them, we had to fight to get them back. So, when they were finally returned, I didn't get any specifics on their condition and longterm care. They are healthy now, 4.5 months old. but both still show some effect. there noses are always runny or crusty (one even gets yucky green "boogers" like humans can). one's eye doesnt like to open all the way. She had only mild eye infection. no discharge now, she just winks. the other one, he got it severe, he looked like he went 10 rounds with a boxer, nearly lost his eye. now he keeps his wide open, but there is constant clear discharge. Since they have been back home now for nearly 2 months, and still show these effects, i am wondering if they will be permanent? is there anything I can do to relieve it?
