Write the next sentence in the following story.

How to take your cat to the vet
Obtain a cat carrier.
Both hard and soft cat carriers will allow you to safely carry your cat to and from the vet. The harder ones are better for vehicle transport.
Training your cat to enter the carrier could take a few hours or a few weeks. In order to have sufficient time to test it out before use, try to obtain a carrier 1-4 weeks prior to the appointment.
