Cat with smelly rear

by Michelle


My cat's butt has gotten stinky in the last couple months. It has like a smudge of poo around it all the time. She is five years old and is overweight. She eats one small can of Fancy Feast and hard food.

I have been washing her butt, but that is getting to be too much, because she really hates when I do that. Please help!! Is there anything I can do about it? Do you know why this is happening?

I will try anything. I cannot afford a vet at this time.

Thank you so much,

Dear Michelle,

Since your cat is overweight, she is likely not cleaning herself well around her rear. There is also a possibility that her feline anal sacs are impacted, especially if there is discharge in the area, which would need to be addressed by a veterinarian. Also, if she has cat diarrhea or slightly loose stool, any stool that sticks to her fur will cause some odor.

I would recommend continuing to wash her rear for her until you can take some weight off her. However, she really should be seen by a veterinarian to be sure she does not have parasites or an anal sac problem.

To reduce her weight, I strongly suggest you cut out dry food because it is high in carbohdrates which is not suitable for cats who are carnivores. It also does not have enough moisture in it. Cats do not ordinarily drink enough so it is important for them to have moisture in their food. Canned food, instead of dry, will add water to her diet. By lowering the carbohydrate percentage in her diet, she will most likely slim down.

It is very important, however, that a cat not lose weight too rapidly. Rapid weight loss in an overweight cat can lead to hepatic lipidosis (fatty liver syndrome) which can be fatal. A cat should not lose more than 1/2 pound per month. Weighing your cat on a digital scale regularly is the best way to monitor her weight.

Between weight loss, cleaning her rear, and seeing a vet about possible anal sac problems or diarrhea from such things as parasites, you should be able to clear up her problem.
