I'd be nervous with anything under about 5" being around a cat.
With Spot, who's about 7", I worry about the cat. Usually he's an indoor cat but from time to time he goes out with us in the back yard. The other day I saw Willy the cat lapping water out of the pond. As his little pink tongue lapped up and down, Spot took notice began his approach, with blood in his eye. I snatched Willy away just in time!
