The world loves grumpy cats (just ask Grumpy Cat herself). We tend to think of our feline friends as sassy, independent, and apathetic creatures—and for many cat lovers, that low-key attitude is all just a part of their charm. But are our cats really unhappy? In honor of Happy Healthy Cat Month, here are six ways you’ll know if your cat is living his best life (even if he’ll never admit it).

One popular myth about cats is they’re happiest having the freedom to go outside. This is far from the truth. There are many cats who are born and raised indoors who have no interest in going outside and would panic if they found themselves on the wrong side of the door.

If you feel your kitty should roam the great outdoors, you’re not alone. Many cat lovers feel their cat is happiest lounging in the fresh air or stalking unsuspecting prey.

However, there are many reasons why it’s safer for your kitty to stay inside - traffic being one - and many cat owners are realizing the dangers of life outdoors.

You get a reminder email, text, or postcard -- your dog or cat is due for a vaccine or two. Time to make an appointment! You arrive for a simple visit with your healthy pet, and then a Licensed Technician or even the doctor begins a full, thorough exam.

Does your kitty panic at the sight of the cat carrier? A lot of cats do. You bring it out and suddenly your cat is squeezing himself into the world’s smallest hiding place or becoming a raging lion hissing and swatting - claws out - at anyone who tries to come near him.

Yeah, we’ve experienced that too.

If you laugh at the idea of getting your couch potato kitty into an exercise routine, consider this: an overweight kitty is at risk for serious health issues. In fact, excess weight increases your kitty’s propensity toward diabetes, joint disease, and even urinary tract problems.

Are you seeing lumps, bumps or growths on your pet? No matter what you call them, masses of all kinds, from harmless skin growths to malignant tumors, are actually fairly common in our furry friends.

How Does Your Veterinarian Examine Lumps and Bumps?

While most masses are benign, we recommend examinations and fine needle aspirates for all new growths. This simple procedure allows the veterinarian to determine the nature of the growth by collecting a sample of cells and viewing them under a microscope.

Creating a cat-friendly home requires an understanding of normal cat behavior and how humans may inadvertently create stress for feline companions. This is important not only because it is nice to keep our pets happy, but also because multiple studies now show that stress can lead to a variety of chronic medical conditions. Ensuring that our pets are well adapted to an indoor environment is a vital part of preventative medicine.
