Consider the material your carrier is made of; cardboard or fabric carriers may not be sturdy enough to transport your cat in (remember they have sharp claws!)
Check all catches and locks are in full working order, the door and lid should always be locked during transport
Cleaning
Your carrier should be easy to clean and have a leak proof bottom
Absorbent bedding can be placed in the bottom of the carrier for your cats’ comfort and to help mop-up and accidents
Access
Carriers that open both at the front and the top are recommended, this gives your cat options when entering and exiting the carrier
Choosing a carrier that can be taken apart allows us to examine your cat in the safety of their carrier if they are feeling worried about coming out
Size
Your cat should be able to turn around within the carrier but not have so much room that they may fall over when they are being carried, this could mean you need to get a new carrier when your kitten grows and reaches full size
Privacy
Some cats prefer to hide away whilst others like to see out of the carrier, covering your carrier with a blanket is an easy option to offer privacy whilst providing ventilation.
Carriers with no ventilation are not recommended (i.e. plastic household boxes)
