The Smiths Medical Slippery Sam Tomcat Urinary Catheter is a 3.5 Fr, 14 cm PTFE (Teflon) urethral catheter designed for male cats. Its highly lubricous shaft supports smooth placement and is rigid enough that a stylet is not required. The open endhole design with no side holes allows direct drainage. Single-use construction makes it a straightforward choice for feline urinary catheterization in clinical settings.
