Catnip is completely safe for your feline. Ours is grown fresh and organically on the farm at Growin’ Crazy Acres in Brooksville, Florida.
The active ingredient that makes cats silly is an essential oil called nepetalactone. Interesting side note, researchers say that nepetalactone is naturally about ten times more effective at repelling mosquitoes than DEET.
Note: Some cats are not sensitive to catnip.
