Bentonite cat litter, known for its clumping properties, can pose health problems, particularly if ingested during grooming. Some cats may also have sensitivities to the sodium bentonite used in this litter, which can lead to gastrointestinal issues due to its natural expansion when it comes into contact with moisture. Signs of a blockage include diarrhea, vomiting, inappetence, and lethargy.

On the other hand, silica cat litter, highly regarded for its moisture absorption and odor control, comes with its own set of health concerns. It is typically composed of silica gel containing crystalline silica particles, which cats might ingest while grooming. This ingestion can result in digestive discomfort, and constant exposure to silica dust may irritate a cat’s eyes, nose, and throat, potentially leading to long-term health problems like cancer [2].

Given these health risks, it’s crucial to explore alternative, safer litter options to ensure the well-being of both pets and their owners. Always prioritize your feline companion’s health and comfort.
