Cats can eat cooked potatoes especially the baked, boiled, steamed, or mashed ones without any toppings, salt, spices, herbs, or any other harmful ingredient.

While extracted and dried they are often referred as to tapioca is a grain-free binder and source of carbs in some cat foods, one source regards it as a low-grade filler, and notes that it is converted to sugar very fast.

However, quality brands such as Purina Beyond Grain-Free, Natural, Adult Dry Cat Food, and Purina ONE True Instinct Grain Free High Protein, Natural Formula Adult Dry and Wet Cat Food have cassava, making it a good option for grain-free feline foods.

However, moderate levels of tapioca in cat food or its consumption is safe cats. Therefore, unless well prepared, your kitties should not be given cassava.

Avoid a lot of tapioca or cassava since these pets are carnivores that require very small amounts of carbs and sugars.

Including a small amount of jicama is often recommended because “it is a good source of dietary fiber and it is a source of Inulin which can be used as a prebiotic to aid digestion,” notes

However, according to Wikipedia “seeds and stems of several plants, such as the jicama vine plant” as well as roots of several of the bean family Fabaceae has rotenone, a naturally occurring pesticide and insecticide.

“In veterinary medicine, rotenone is used in powder form to control parasitic mites on chicken and other fowl, and lice and ticks on dogs, cats, and horses, states Science Direct.

While we have noted that tapioca, arrowroots, jicama, sweet potatoes, and potatoes are safe for these pets, they should be only a small part of your feline diet because these pets are strict carnivores and none of these tubers are part of their natural diet.

Also, felines do not need foods high in starch or carbohydrates often high in dry cat food as opposed to wet ones.
