Cats are crepuscular creatures, so your kitten is likely to be most active during the early morning and late evening. That means they might be keeping you up or waking you up early.

Your kitten’s behavior can change drastically from moment to moment when they are this age. They can tucker themselves out and take a nap, waking up wound for sound and ready to go.

The 5 Tips for Your 5-Month Old Cat

Are you wondering how you can interact with your feline at 5 months old? Here are some areas you can focus on.

1. Never Stop Bonding

This is a crucial time in your kitten’s overall development. You should be bonding with them continually to build that relationship. You might play, cuddle, speak in a soothing voice, or all of the above! These are all incredible ways to get to know your cat and watch them develop as the days pass.

When your kitten fully develops, you two will have a best friend bond with no doubt! They will thrive on your companionship, and the two of you will learn how to interact with one another in a way that suits you both.

2. Have Lots of Toys

Don’t find yourself short of entertainment. Your cat is going to require lots of things to do, and it is your job to make sure they have enrichment. At this age, they’re going to be interested in a variety of activities, and they won’t really be picky about when they engage in play. Rotate these toys out every couple of days so that your kitten always has something “new” to play with.

Their predatory instincts will be on sharp alert, so they might want to pounce, jump, and attack anything that they find moving. You might find hair ties, paper clips, and a plethora of other small items that get pushed underneath your couches, refrigerators, or stoves. Do your best to keep these small items out of reach of your kitten as some will go as far as swallowing them which can lead to intestinal obstructions.

To keep their interest peaked, you should offer puzzles and other entertainment forms to satisfy your kitties. Keep in mind that some cats respond very well to catnip, and others don’t have a reaction. If you haven’t tested out catnip yet, this might be a good time to do so.

3. Keep Your Kitten Stimulated

Don’t let your kitten get bored. Often, people find that having two kittens actually alleviates a lot of the responsibility. If two kittens are together, their energy levels will match quite well, giving them both an equal outlet. However, if you don’t have another kitten in the home, you can keep them engaged in other ways.

Kittens will likely be destructive if left to their own devices for too long. You will always want to have a way to keep them contained when no one is home and keep anything that they might get into out of their reach when no one is around to supervise.

4. Be Sure to Keep Up with Routine Vet Visits

Your kitten is going to get to know their vet very well in the first year of life. They’re going to have to go for routine shots, general checkups, spay or neuter surgery, and microchipping. At 5 months, you should be already thinking about scheduling their spay or neuter.

Getting your cat fixed before they reach sexual maturity is always a good idea to avoid unwanted pregnancy and behavior-related changes.

5. Consider Pet Insurance

Do you have an insurance plan for your cat yet? If not, it’s certainly something we recommend looking into. Even though you might think that it’s unnecessary, there are several perks to be gained from getting insurance for your cat. At 5 months old, they likely don’t have any diagnosed health conditions.

However, the older they get, the greater chance one could develop. If your cat has a preexisting condition, it may be near impossible to get a policy that will cover the costs for it. If your cat has no known medical conditions at the time of enrollment, they will be covered for everything you choose to put on your policy.

Some people just choose emergency-related illnesses, conditions, or injuries. Other people want wellness care plans that cover general vet visits as well. You can get as intricate or as simple as you want, but the coverage is still so comforting.

Most insurance companies charge around $20 to $30 per month. You can also bundle plans with yours if you have insurance through companies like Nationwide or Progressive.


So now you understand a little more in-depth what to expect when your kitten is 5 months old. Trust us, these days will fly past you, and you will barely remember what it was like to deal with a furry juvenile delinquent living in your household.

Remember, if you haven’t done so yet, make an appointment for your cat to get fixed. We don’t need any unplanned litters!
