I have 2 cats at the farm. If I do not make sure to keep them in the garage when I go out hunting, even before sun rise, they will follow me all the way to the tree stand and play around at the base of the tree the whole time I am in the stand.
I have never seen them pay any attention to my hives, probably learned their lesson when I was not around.
The first year the I got my bees, I saw our service dog, Radar, sniff the hive entrance, only once, pulled his nose right away but showed no sign of being stung. He never did it again.
