How do cats respond to silver vine?
A cat’s response to silver vine typically involves rolling around on its side or back, giving cheek or chin rubs, bunny kicking and sometimes minor drooling. The cat wants to stay close to the source of the smell and probably wants to engulf itself in the aroma! The response, however, depends on a few things. The first one being the cat. Not all cats respond equally. There may be genetic or personality traits that affect how and if the cat responds.
Furthermore, how a cat responds depends on which part of the silver vine plant is offered to the cat. Silver vine fruit galls are the part of the plant that your cat will love most! Stem (wood), leaves and normal silver vine fruit contain much less of the compounds that produce the smell than dried silver vine fruit galls do. Fruit galls are funny looking fruits that look unusual because of insects having attacked the fruit. If there are no insects attacking the fruit, the fruit would have a more normal appearance and the plant would not produce fruit galls. During the attack the plant will protect itself by producing a lot of smell compounds to deter the insects, and most compounds are produced in the fruit.

How often should I let my cat play with the silver vine toy?
As with anything in life, we get used to things. You may not hear the clock tick anymore or the train passing by because you have been hearing it so many times. The same is true for smells we get used to them. It is no different for cats! When cats are continuously exposed to the smell of silver vine (or catnip), they will get used to it and it will become less special for them. Therefore, it is recommended to offer the toy to your cat only a couple of times a week for no longer than about an hour. It is believed that cats who respond incredibly intensely at first, get used to the smell quickest.
Can my cat eat silver vine?
It is not recommended to feed silver vine to your cat, simply because the effects of eating silver vine have not been studied. However, accidental ingestion of silver vine is no reason for concern. As is true for anything you see your cat ingest, when you see your cat showing abnormal behavior or signs of distress in response to ingestion of silver vine (coughing, excessive drooling, not eating, inactivity, not playing, excessive meowing, etc.) always contact your veterinarian.
