There are a wide range to choose from – wicker, solid plastic, fibre-glass, plastic-coated wire mesh etc.
Where possible, it is always better to leave your cat either at home with a sitter or at a boarding cattery.
Most cats are not particularly happy travellers – they are usually bonded strongly to their own territory and feel very vulnerable off home ground.
The rewards of staying with the family 'pack' or the potential of exploring or walking somewhere new at the end of the journey do not excite the average feline in the same way as its canine cousins.
A useful method is to leave the carrier out, with a blanket, some treats or toys and let your cat explore himself.
As he becomes familiar with the carrier, shut the door for short periods of time.
