Will a four-month-old kitten defecate on its own? Yes, a four-month-old kitten will defecate on its own. Kittens usually start defecating on their own around one month after birth.



If your kitten isn't potty trained, you can use a cotton swab or a tissue dampened with water to stimulate it to defecate. Once the kitten can potty train on its own, you can start training it to use a litter box. Some kittens don't need to be trained; they'll use it instinctively.
