If guinea pigs take in excess fiber from kale, it can result in diarrhea or other digestive problems.

Abnormal Thirst

Kale causes an increase in the frequency of thirst in a guinea pig.

Due to a large amount of sodium (Na) And potassium (K) ions in kale, these ions absorb water and neutralize themselves which causes water deficiency in the body.

Vitamin K promotes and facilitates muscle contraction.

Kale is a good source of vitamin K but more than required vitamin K can cause problems related to muscle contraction and muscle relaxation.

If you meet any issues related to muscle, take professional advice.
