I have a kitten who is maybe just but probably less than 6 months old she was the runt of the litter and she got a cold/flu/etc its terrible you can hear the congestion from across the room her eyes at a point earlier got so covered in mucus they were shut i had to open them myself she sneezes and coughs very badly and sometimes a white-ish mucus drool type thing comes out of her mouth when she coughs hard, we wipe her nose and eyes a few times daily and try to keep her under blankets and warm she hasn't eaten or drank much at all even wet food shes been like this for maybe 5 days. you can literally hear the congestion with every breath she takes. help!! what can i do? give her some sort of over the counter medicine or what??
