There are a few cats that hang around my apartment complex. We lept hearing squeaking for a couple days and after seeing a dead newborn, we decided to find the one still squeaking and bring it in. We found a very weak kitten with its umbilical still attatched. My girlfriend and I brought it in, nursed it with the proper formula, cuddled it all that. Last night, around 4am I turned the heater off for the kitten because I couldnt sleep it was too hot. We had kept it around 80 degrees in the room for the kitten but when i turned the heater off I imagine it probably dropped to around 65. (i wasnt really thinking too well, it was 4am and I couldnt sleep). Anyways, its 1pm now and the kitten is dead. Could a 20 degree drop kill a kitten? I mean, this thing was in the cold basement for 2 days before we even picked it up.
