A kitten's strong cat feces odor may be due to an overly dirty and unsanitary living environment. The following measures can be taken to improve this:
Clean the cat bed: Clean the cat bed and cat litter in a timely manner, change the cat litter regularly, and clean the cat litter box regularly.
Switch to cat litter with stronger odor control: Choosing cat litter with stronger odor control can reduce the smell of cat feces.

Spray deodorizer: You can spray some deodorizer around the litter box to help mask the smell of cat feces.
Regular bathing: Kittens can be bathed regularly using shampoo specially formulated for cats to help remove dirt and odors.
Keep the room well-ventilated: Maintaining good indoor ventilation helps air circulation and reduces odors.
