Choosing the best carrier is a big decision. It is not recommended to force your kitty in our dump them out of the carrier, this makes carriers with a top door a good choice.
The carrier needs to be seen as a safe comfortable place. Keeping it in a familiar place in your home with kittys blankets, toys and even adding treats can help make sure that its not associated with stress.
Using a Feliway wipe can help decrease the stress your cat feels when using his/her carrier
