Trocars for Feline Laparoscopy: Why Cats Deserve a Different Approach
The feline abdominal wall is considerably thinner than that of most dogs and the skin is far more elastic. As a result, the amount of resistance encountered during trocar insertion is much lower.
Traditional sharp trocars rely on a controlled puncture using an obturator. In larger patients, this technique is predictable because the body wall offers greater resistance.
In cats however, tissue resistance can reduce suddenly during insertion, making it easier to create more tissue disruption than intended. While experienced surgeons adapt their
technique accordingly, the choice of trocar can also influence how controlled that initial entry feels.
