Cats are known for their independent and often mysterious nature, which can make it challenging to spot when they’re not feeling their best. As responsible pet owners, it’s crucial to be vigilant and attentive to your feline friend’s well-being.

Recognizing the 10 Warning Signs Your Cat May Be Sick can make a significant difference in their overall health and happiness. In this blog post, we’ll discuss ten common indicators that your cat might be unwell and when it’s time to seek veterinary care.

These 10 Warning Signs Your Cat May Be Sick are a must-read for any pet owner!

10 Warning Signs Your Cat May Be Sick!

  1. Changes in Appetite:

One of the earliest signs that your cat may be feeling under the weather is a change in their appetite. A decrease in appetite or refusal to eat can indicate various underlying issues, from dental problems to digestive disorders.

On the flip side, increased appetite and excessive thirst can also be red flags for conditions like diabetes or hyperthyroidism.

  1. Weight Loss or Gain:

Sudden or significant weight changes are cause for concern. If your cat is losing weight despite eating normally, it could be due to an underlying health issue, such as hyperthyroidism or gastrointestinal problems.

Conversely, unexplained weight gain may be a sign of conditions like diabetes or hypothyroidism.

  1. Lethargy:

Cats are known for their playful and active nature. If you notice your cat becoming unusually lethargic, spending more time sleeping, or not engaging in their usual activities, it’s a sign that something might be wrong.

Lethargy can be a symptom of various illnesses, including infections and organ diseases.

If you notice any unusual or concerning changes in your cat’s behavior, appetite, or physical condition, don’t hesitate to contact your veterinarian. Early detection and prompt treatment are key to ensuring your cat’s long and healthy life. Remember, your veterinarian is your best resource for addressing your cat’s health concerns and providing the care they need to thrive.

    This is a really great post. My cat Sammy had a bout with pancreatitis and went off food for a day or two but I knew something was up because his pupils were very dilated. We took him the to vet and just needed to get some IV fluids and treat him symptomatically and give him some antibiotics just in case. Scary though!

    A cats personality changes so much when they are sick. I always say the minute a cat stops acting like they are in charge is usually when you should start worrying, laugh.

    My husband says that another way to tell is by the color of their tongue. If it isn’t a bright pink, then that could be a sign that they are sick.

    Wonderful guide to detecting illness in your cat. My cat used to disappear and hide when he was feeling poorly. I believe this is an instinct where weakness in the wild means becoming an easy target. I see this often in dogs and horses as well. Very important information to have.

    Thank you for sharing this information. I was familiar with everything except the dilated eyes. Truffle and Brulee’s eyes are dilated a lot because there is little natural light in my home and it’s dark.

    Cats are very good at hiding pain and illness. I urge anyone who sees one of the signs that you’ve listed to investigate the cause. Go to the veterinarian for help. Get wellness check-ups so the veterinarian can see the early signs of developing problems. My angel kitty, Cinco, had no signs of his cancer until it was too late. I tend to beat myself up because I passed on getting some tests done (for financial reasons) at his last wellness exam that could have told us he was in trouble. He seemed perfectly healthy all of his 10 years until suddenly one day he wouldn’t eat. I had to help him to the bridge 2 days later.

    In my experience with cats we’ve experienced most of those symptoms. There’s nothing worse than being woken up in the middle of the night by a cat’s projectile vomiting. But, my tortie Saffie hid her oral cancer from us for months. It was only after I had to say goodbye that I could see all the signs that something was wrong but it was too late.

    It’s the subtle signs we have to watch for, as you point out. Long ago, I used to think litter box issues were always behaviorial, but when people ask litter box questions now, I ask them to rule out medical issues first. One of the biggest ways cats let us know something isn’t right. When my Bo was aging, how I wish I’d known then what I know now, could’ve done so much more to help him.

      We all have those regrets Karen. Our cats are so good at hiding their pain and we figure it out too late so often. You will snuggle Bo again one day, I promise!

    I lost Nala to kidney disease at 19+ and I did not really realize she was so sick until she peed pink on a white carpet shortly before she passed- she never had accidents so straight to the vet.

    You always have to be aware of anything different with your Cat,after our cat was not moving around much for a few days a trip to the vet and we found out his front paw joint was being attacked by micro-organisms ,a quick operation to clean out the joint and some steroids and he should be fine in a few days,but been told it could flare up again but maybe not for years.

    A great list of things to watch for in a cat. Our cat would hide on us when he was sick- we even missed a vet apt while trying to find him in the house. We did finally find him and take him in and it was an infection in his mouth and a couple days of antibiotics and he was back to normal.

    It’s good to know that our cat may be sick if they’re normally awake but start sleeping constantly, or vice versa. My husband has had some time home from work and said our oldest cat started sleeping an abnormal amount over the weekend. Thanks for letting me know that we should get her checked out at an animal hospital soon for peace of mind!
