Best Cat Food for Constipation Buying Guide

As stated earlier, you need to know whether your cat is suffering from constipation before you subject her to this special diet that we have reviewed above for you. This is because some of such diets require a special veterinarian prescription before you can purchase them.

Poo from a healthy cat is normally dark brown in color, firm but soft in texture with a slightly pungent odor, but nothing too smelly. Therefore, it should now be able to tell a change in this, and that should notify you of an impending health crisis if not checked on time.

The following are some of the signs that will show your cat is constipated:

Infrequent or no defecation

Constipation is a condition that makes it hard for the poop to come through the anus. This is because it is actually very dry and too hard for the anus muscles to push it through. When your cat tries to force the poop through, it will suffer pain.

The pain may even lead to cracking of the walls of the anus resulting in a more painful experience that your cat will not be able to bear. Fearing this, she will either defecate infrequently, or she may not even defecate at all.


Your cat will strain when doing a lot of things. Come to think of the pain that your kitty will be going through during egestion. That will suck up to her energy, and she will have no morale in doing things. Therefore, she will ben straining too much.

Hard, dry feces

Your kitty will give out hard and dry faeces. The explanation in this is simple because the food that she fed on did not have fiber. Fiber adds moisture and bulkiness to feces, thereby making the process of egestion easier and more relieving.

Defecating outside the litterbox

Normally, your cat will defecate in a designated litter box that she had been trained to use from a younger age since she was a kitty. When this habit changes and she start defecating outside the box, then it means that she is no longer comfortable, and she is straining.

Small quantities of feces

It is quite apparent that any pet that is constipating will give out small amounts of feces your kitty not being an exception. This is enough sign to raise red flags and should check on the wastes to see whether they exhibit any chances of constipation.

A small amount of liquid stool with mucus or blood

Since constipation is a condition that makes it hard for passage of stool, it is likely to cause harm to the internal organs around the rectum and the anus. Therefore, the stool might be excreted with traces of blood and mucus from the collapsing tissues.


If your cat is suffering from constipation, she will be vomiting every now and often because the food in her stomach will not be completely digested. Constipation causes incomplete digestion, and there will be no room for other food.

Lack of appetite

When no food is passing out of the body, there will be no room for other food. That is what constipation causes tom your cat. That will drastically reduce her appetite, and she will have a low intake of food or no intake at all.

Behavioral changes

Behavioral changes are a common thing for all the cats that experience uncomfortable conditions. But for constipation, you will easily notice as your cat will lose interest with almost everything, including her toys. She will seclude herself due to stress and pain. 

Causes of Constipation in Cats

Anything that is related to the digestive tract has to be caused by something, most probably the food that passes through the alimentary canal. The following are the known possible causes of constipation:


Blockages are a common thing that will likely be caused by foreign materials that your cat may ingest accidentally. This may include hairballs that are so common in domestic cats since they love grooming. This may block vital parts of the alimentary canal.

Reluctance to use the litterbox

This happens typically because of stress and change in mood, but it can also be caused by excess litter in the litter box. They may also refuse to use the litter box due to pain in their joints, which is discussed in the detailed form under arthritis.

Lack of exercise

Generally, enough exercise will always be a healthy remedy for your cat. Regular exercise enables the food in your cat to move freely and swiftly hence preventing any chances of incomplete digestion that may trigger unnecessary constipation.

Nerve damage

Though not a common cause, nerve damage can also lead to constipation. This may be possible if your cat has recently been in an accident or if she suffers a long-term condition which may result in nerve damage. The nerves that control excretion.

This nerve communicates to the sphincter muscles in the rectum to release the feces through the anus. When the nerve is damaged, there will be no communication, and that means that there will be little egestion or not at all.


Dehydration is a common cause of constipation. Your cat will always need plenty of water to moisten the food matter that is indigestible for easy excretion. That is why fiber plays a major role in absorbing excess water from the colon to lubricate the feces.


Arthritis is a condition that will normally be experienced with old felines, which includes sharp pain in the joints when squatting. An older cat will always avoid going to the toilet just to put off the pain as it will be very uncomfortable for her.

Unfortunately, when this habit continues for long, it will cause the feces to dry and become more painful to move, which then creates more issues with your cat. This will possibly lead to constipation.

Therefore, it should be very easy to tell whether your cat is suffering from constipation or not thanks to the review. The causes of constipation will also help[p you prevent the occurrence of the same by making sure that such causes like dehydration do not hit your cat.
