If a cat who normally reacts to catnip is in a strange environment or is anxious, she may not react to the catnip. No one really understands the genetic trait, but it can be bred into a line through genetic selection. This substance closely resembles a chemical found in the urine of female cats. This may be why unneutered males generally have more of a reaction to catnip than females and neutered males. Give it no more than once a week or the effects diminish.
Cats love it green and fresh.
Bruise it slightly before giving freshly cut stems or leaves. If using dried catnip, store it in a sealed container in the refrigerator and give a heaping teaspoon per cat weekly. Inc. All rights reserved.
