They all have some respiratory and eye infection but only one (the grey) one seems to be critical
The vet at the animal rescue said that he’ll hopefully get better over the weekend but he is still critical

He also has a painful infection at his private parts. They all seem to have herpes but they may grow out of that.





I am sorry I didn’t realize that until after I commented just from the pic on the post. Hope they do well. Best of luck.
Is it bacterial? Because antibiotic eye drops work great, for me at least when I have gotten eye infections from swimming.
No worries!
The vet says it is cat herpes so they need to fight it off themselves. So hopefully good food, warmth and water will be enough. We do clean them several times a day though with drops and cotton swabs
I could be wrong and it might depend on their age, but I believe famciclovir can be used by kittens, and it can tremendously helpful with feline herpes. It might be worth seeing if the vet would be open to trying it! (One of my little guys had a severe case as a kitten and the rescue used it to bring him through it, but I’m not sure how old he was when they started the course. I adopted him at six months.)
Sometimes herpes is mis diagonosed, as, what is it, I forget, look into it. Impleglio, not that, impetigo, something like that.
