Hi there, I rescued a homeless kitten who we had been feeding for a couple of weeks. We've posted all over looking for his home (if he has one) and are taking him to get checked for a microchip tomorrow. In the meantime he is in our bathroom since the temperature is dropping dramatically outside. We noticed that one side of his mouth or face is newly swollen (within the past few days, definitely new this week). He is also drinking a lot of water. I will take him to a vet but it is Sunday and they are all closed. I am wondering if anyone has any ideas in the meantime. He appears to have been living outside for a while, on his own, not part of a colony. He is a kitten, maybe about 6-7 months old. We had an older cat die of oral cancer a few years ago so I am worried about the little guy.
