| They are cats. They have fur coats. Just leave it at whatever you normally leave it at when you go out. At my house that's usually 63. |
| 70 is way too high! We leave ours at 64 in the winter when go on a winter vacation. Unless you have a really old cat who's very skinny and always seems cold. |
| OP here. Thanks. Will keep at 60. Young, kind of fat cats. |
