My cat hates the car and his travel box (plastic with wire mesh). He claws at the boxes air vents / grill and goes a bit crazy when we drive, which leads to pulled off claw sheaths and a bit of bleeding. How do I stop him from doing this? Is there any solution other than sedating him?
I would suggest cutting the cat's claws immediately before transporting him. Make sure to use proper clippers designed for use on cats. Another suggestion is to get a different cat carrier, one that the cat is less likely to get their claws caught on. They make tote bag type carriers that are constructed from heavy cloth materials like nylon rather than hard plastics, which may work better for him. You could also try covering particular problem areas with a towel or something, as long as it doesn't block all the carrier's ventilation. Cloth is of course porous, so air could get through, but it might become too hot if all openings are completely covered.
