For the safety of your cat, always travel with it in a carrier. Carriers come in several styles. The most economical is a simple cardboard carrier, often available from your vet or pet shop. Hard plastic or fibreglass carriers last longer, are more secure, easily cleaned and disinfected, and fold away for storage. They are warm and cosy and provide a feeling of security for the kitten. Wire carriers are easy to clean and their openness allows for air circulation in the summer, but they can be cold in the winter and provide little refuge for a frightened feline.
