Cat Channel.com's Arnold Plotnick, DVM, recommends these sprays to calm cats during car travel and to accustom them to stressful environments.
They are available through some pet stores and veterinary offices.
This product contains Valarium which relaxes all pets and has even had some effect on us as owners!
This is a natural product that mimics the pheromones cats release to reassure others and reduce stress levels.
If you spray this in the cat basket and car at least half an hour before travel, it should help relax your cat when they enter.
Leave the basket out days prior to travel so that they get used to the box and if possible, try feeding him or her a meal or laying treats inside for them to find so they can associate nice things with the cat box.
Alternatively, if you notice signs of nausea such as drooling or vomiting when travelling, please book an appointment with one of our vets so we are able to prescribe some anti-nausea medication.
