"Catnip has made a big impression on the pet industry, and every store should stock lots of in in many different forms. Catnip is a tremendously important item in the pet industry, as it can be sold to cat customers for a variety of reasons. When catnip is combined with toys, (such as Nip n' Toy), it creates an added interest for the cat.
For cats, the biggest benefit of play is exercise and the resulting fitness. The health benefits of exercise are more easily obtainable when catnip is used as a tool to help entice the sometimes less than active cat. Planned play periods can also have a huge affect on the human animal bond, strengthening the relationship between the two.
The catnip used with toys to encourage more interactive play with also help with curbing disruptive behaviors, such as pouncing, jumping and biting, as well as the scratching of furniture, drapery and walls. Catnip toys represent the most common use of the catnip product for consumers. Stock heavily on catnip toys- they all sell well."
