Cats are masters at masking symptoms when they’re sick or in pain. It’s business as usual, when in reality, it’s anything but.
That’s what makes it so important to know and understand signs your cat is sick. Not only will you or your sitter be able to help them feel better but you can prevent anything from worsening by taking them to their veterinarian. Learn common signs of sickness and how our soft cat carrier at Cat-in-the-Bag can help with vet visits.
Their Grooming Habits Change

Grooming in and of itself is not a problem. But if your cat is doing more than usual or has created bald spots, it’s usually a symptom that your cat is sick. Their skin may also appear red or have a rash. This could be an indicator of allergies, a parasite like fleas or mites, or even a sign of cat stress.
Alternatively, your cat may also not groom themselves as well. You may see a messy coat or mats of fur.
They’ve Gone MIA
Is your cat nowhere to be found? Or maybe less social than normal?
Withdrawal is a subtle symptom sick cats display. They hide and withdraw to help themselves cope and conserve energy when they’re not feeling well. However, this very much depends on your cat’s personality. Some may get clingy. Some may just get cranky!
You Notice Litter Box Issues
Any big changes in litter box habits is a sign your cat is sick. This includes both diarrhea and constipation. While the first is more obvious, constipation can be harder to catch. Their stool will usually be small, hard, or dry if they’re constipated.
Other litter box-related symptoms sick cats show include:
- Changes in frequency (more or less)
- Vocalizing when using the litter box
- Urinating outside their box
- Blood in their urine or stool
They Have Runny Eyes and Nose
Sometimes, sick cat symptoms can mimic that of humans: sneezing, coughing, sniffles, or runny eyes. These symptoms are often a sign of Feline Upper Respiratory Infection, or “cat flu.” Think of it like the common cold.
Mild symptoms usually go away on their own after a few days with rest, humidifiers, and home care. However, we always recommend calling or visiting your vet at Cat-in-the-Bag. They can diagnose your cat’s sick symptoms and provide the proper care.
They’re Lethargic or Less Playful

Sick cats also often have less energy. They’re less interested in play. They’re sleeping more or sleeping in unusual places. Some may also avoid human contact when they’re not feeling well.
There Are Changes in Appetite
Notice your cat is uninterested in their favorite treats or food? Take note; this is a common symptom of sick cats. Loss of appetite could signal a range of illnesses, from dental pain to digestive problems and stress. So be sure to see your vet if it lasts for over 24 hours.
Cats may also experience increases in appetite when they’re ill, which is often a sign of things like diabetes and hyperthyroidism.
They’re Drinking More Water
Drinking lots of water is normal, right? Well, it depends. Cats generally drink about 4 ounces of water per 5 pounds of body weight. So if your cat is 10 pounds, that’s a cup of water each day. Large and very active cats drink more.
It’s also normal if your cat drinks more water on a hot day or you’ve recently started incorporating more dry food.
But if you’re refilling their water bowl multiple times a day or they’re running to the faucet each time you turn it on, you may want to consult your vet. It’s often a symptom that sick cats exhibit.
What Can You Do For Your Cat?

Because signs your cat is sick can be subtle, it’s best to err on the side of caution and make your way to the vet. They know what’s normal (and what’s not) and provide the right care.
Of course, vet visits aren’t often easy on a good day, let alone when your cat is experiencing sick symptoms. We recommend trying our Cozy Comfort Carrier at Cat-in-the-Bag.
While some cats love their crates, others have a fear of confinement that makes getting them into a carrier a big fuss. Our cat carriers are designed with a heads-out design to keep them calmer going into and staying in their carrier. They also feature an adjustable Velcro collar and a snug design to keep them secure at the vet. This makes it great for medication administration!
It makes taking a cat to the vet easier too, thanks to our seat-belt pass-through loop. Just slide your seat-belt and shoulder strap through the pass-through loop and clip them in!
