Yes, there are other plants and substances that can cause similar effects to catnip in cats. Here are a few examples:

1. Silver Vine: Silver vine is a plant that is native to Asia and is often used as a natural alternative to catnip. The plant contains two chemicals, actinidine and dihydroactinidiolide, which are believed to have a similar effect on cats as nepetalactone in catnip. Some cats may not respond to catnip, but may have a positive reaction to silver vine.
2. Valerian Root: Valerian root is a plant that is commonly used as a natural remedy for anxiety and sleep disorders in humans. The plant contains valerenic acid, which has a sedative effect on the nervous system. In cats, valerian root can have a similar effect as catnip, causing them to become relaxed and calm. However, the smell of valerian root is much stronger than catnip, and some cats may not like the scent.
3. Tatarian Honeysuckle: Tatarian honeysuckle is a plant that is native to Asia and Europe. It contains a chemical called nepetalactol, which is structurally similar to nepetalactone found in catnip. Some cats may respond positively to Tatarian honeysuckle, although it is not as potent as catnip.
4. Matatabi Sticks: Matatabi sticks, also known as silvervine sticks, are made from the dried fruit of the matatabi plant, which is native to Japan and China. The fruit contains actinidine, which has a similar effect on cats as nepetalactone in catnip. Some cats may prefer matatabi sticks over catnip or silvervine.
5. Cat Thyme: Cat thyme is a plant that is similar to regular thyme, but has a more pungent scent. The plant contains chemicals called terpenoids, which have a similar effect on cats as nepetalactone in catnip. Some cats may respond positively to cat thyme, although it is not as potent as catnip.

It is important to note that while these plants and substances may have a similar effect on cats as catnip, not all cats will respond to them. Additionally, some plants and substances may have different effects on cats depending on the individual cat’s sensitivity and tolerance. It is always best to supervise your cat when introducing them to a new plant or substance and to consult with a veterinarian if you have any concerns about your cat’s behavior or health.
