One of my cats seems to have an adverse reaction to catnip. When it is around, he gets agitated and attacks the other animals and anyone that comes near. It only happens with catnip-infused toys, but when he is exposed to ground catnip from a vial, he has no reaction what-so-ever.
Is there anything that can be done to improve his reaction, since the other cat loves catnip and has the normal, high reaction to it? Should I just avoid getting catnip infused toys for the house, or is there a way to remove the catnip, since everything seems to be infused with catnip?
