Some breeds adapt better to an indoor lifestyle than others, but there are pros and cons to both keeping cats in and letting them outside.
See FAB website factsheet: 'In or Out' – www.fabcats.org
and the website: www.nssvet.org
If cats are kept indoors they will need a litter tray and outlets for their need to scratch and play. Information on scratching in the house is available on a Blue Cross/FAB information sheet available on www.thebluecross.org.uk or www.fabcats.org
The de-clawing of cats in the UK is condemned by The Cat Group. Some products are available through the internet to protect your furniture and even to cover your cat's claws to prevent them causing damage.
