[header] How to bring a new cat or kitten home [title] Purchase a sturdy pet carrier to take your cat home. [step] Your cat will understandably be nervous when you take it home, and a secure carrier can offer an enclosed space to offer comfort and keep your cat safe. [substeps] Some cats vomit or urinate while nervous, so a well-made carrier can protect your car's interior. 
Your shelter or breeder may be able to lend you a carrier for your first trip home. Ask your shelter or breeder for a blanket or towel that your cat has been sleeping with to put in the carrier.
