When they're sick, cats are known for being silent and strong. It is important to be aware of these subtle signs.

She’s MIA "Cats can be very stoic which makes it hard to tell if they are sick." This could indicate that your cat is sick. 

He’s drinking like a fish The average cat doesn't drink a lot of water. They only need about one cup per ten pounds. It's easy to tell if the water bowl is emptying faster or he's trying other sources such as the toilet. If your cat drinks more water than usual, it could indicate that your cat suffers from an endocrine disorder like hyperthyroidism or diabetes. 

She’s turning his nose up on her favorite food "Cats can have many dental problems, including periodontitis, gingivitis and stomatitis. This causes the resorption of many of their tooth roots. 

She’s got runny eyes and nose "If your cat experiences sneezing or nasal discharge, coughing, fever, and the sniffles, it could be due to feline upper respiratory diseases, which is very similar to the common cold in humans." 

He’s more vocal than usual This is not a sign that your cat might be sick. However, it is noticeable if your cat's vocalizations are louder than usual. If your cat's meowing continues for longer than 24 to 36 hours, it could indicate that he is sick. 

She’s losing weight A few extra pounds on a 10-pound cat can be very noticeable. This is a sign you should not ignore. If you see signs of weight loss in your cat's body, make sure to check with your vet to ensure that she has been thoroughly screened for any internal diseases, dental problems, or other conditions that may be contributing to the weight loss. 

He’s losing hair and his skin is crusty Your feline's health is at risk if you notice hair loss or crusty or scaly spots on her skin. These are all signs that your cat has ringworm and you should see a vet immediately. 

He’s letting his dander pile up Cats are excellent groomers so if your cat has dander on his bottom or belly, it's probably an indication that something is wrong. "The most difficult thing for elderly cats with arthritis is losing their ability to properly groom themselves," 

She’s throwing up a lot Cats can vomit after eating, or after consuming too many hairs from self-grooming. Acute vomiting, which lasts more than three days, can cause dehydration. 

He’s just not himself It's hard to pinpoint what it is, but your cat has been acting strangely lately. He seems to be less playful and sleeping more. Although it doesn't seem serious, you start to notice that he is slower at going up and down stairs, using the litter box more frequently, and not jumping up to his favorite spot on his window sill. You may find him vocalizing or irritable when you touch him. 

His breathing is bizarre If your cat is having trouble breathing, watch out for signs such as a swollen belly, a tightened chest, and a wide mouth. Your cat may also have his neck or head hanging low or extend beyond his body. You may also notice rapid breathing and wheezy or raspy sounds. 

He is spending way too much time grooming He's not trying to be vain. Dr. Rossman says that overgrooming (also known as psychogenic hair loss) can indicate illness. There are many types of illnesses, including psychological ones like anxiety, stress, and boredom. It could also be caused by allergies, fleas, food reactions, hormonal disorders, and other conditions. 

You noticed a lump while petting her You should not ignore symptoms such as difficulty breathing, nausea, vomiting, diarrhea, persistent diarrhea, and swelling of the abdomen. 

The cat is known for being the silent, strong type of animal kingdom. This makes it important to watch for silent signs that something might be amiss.
