My sister got 2 kittesn ( ) free from a barn. She said they're sick. They have runny eyes/nose. And like pussy stuff coming out of their nose. And they're weezy I think too.

Do you think it's just a cat cold or do you think it could be like Leukimia? Is that the name of the disease cats get that's really deadly?? I'm not sure of the symptoms of it? If it is contagious, if I went to see them, would I carry it on me and give it to my cats? or would they need direct contact? Or maybe it's not even the same symptoms lol.

Also, is milk bad for them? Appearintly they've been feeding them cows milk at the barn and told my sister to do the same. She said they're 8 weeks and I'm pretty sure they wouldn't even need their mothers milk by that age
