The age of a cat can affect their response to catnip. Kittens under six months of age are less likely to respond to catnip than older cats, as they may not have developed the receptors that respond to the nepetalactone compound found in catnip.

As cats age, their response to catnip may also change. Older cats may become less responsive to catnip, as their receptors may become less sensitive over time. However, this is not true for all cats, and some older cats may continue to respond to catnip well into their senior years.

It’s also worth noting that some cats may never respond to catnip, regardless of their age. This is because the sensitivity to nepetalactone is a genetic trait and can vary from cat to cat. It’s estimated that about 30% of cats do not respond to catnip at all.

Additionally, it’s important to note that while catnip can be an enjoyable and safe treat for most cats, not all cats react positively to it. Some cats may have an adverse reaction to catnip, leading to vomiting or diarrhea. As such, it’s important to introduce catnip to your cat slowly and monitor their behavior closely to ensure they’re not exhibiting any concerning symptoms.

In conclusion, the age of a cat can affect their response to catnip, with kittens under six months being less likely to respond, and older cats potentially becoming less sensitive over time. However, it’s important to note that not all cats respond to catnip, and some may have an adverse reaction to it. As with any treat or supplement, it’s essential to monitor your cat’s behavior and adjust the amount given accordingly. If you’re unsure about giving your cat catnip or how much to give, it’s best to consult with your veterinarian.
