Here are some things to consider:
* How much more is your cat sleeping? A slight increase in sleep is normal, but if your cat is sleeping almost constantly, it could be a sign of something else.
* Are there any other changes in your cat's behavior? Changes in appetite, energy levels, grooming habits, or litter box use can also be indicators of a potential health issue.
* Have you noticed any other symptoms? If your cat is exhibiting any unusual behavior, such as lethargy, vomiting, diarrhea, or difficulty breathing, it's important to consult a veterinarian immediately.
If you are concerned about your cat's sleep patterns, the best thing to do is to schedule a visit with your veterinarian. They can examine your cat and determine if the increased sleep is due to age, a medical condition, or something else.
Remember, it's always better to err on the side of caution when it comes to your pet's health.
