I'm getting into the first fall season with my kittens (5.5 mos old). Last night was the first night it felt cold - it was maybe 45-50 degrees outside. I prefer cooler temperatures and usually cover up with an extra blanket or put more clothes on until I absolutely need to use the heat...but I want to make sure the cats are comfortable - and they have all that nice fur, but does anyone know app. what temperature they start feeling uncomfortable?
