If she's an older or a heavy cat, declawing should really be the last option. Her claws should be trimmed whenever they start getting long-every couple of weeks. your vet can show you how to do that. It's very easy and doesn't require anything other than the nail trimmer you use for yourself. One scratching post probably isn't enough. It may not be tall enough, be covered with a material that she wants to scratch, etc. She could be bored and she is certainly marking her new territory. We have six indoor only cats, none are declawed and we have very few issues with clawing. However, we trim nails frequently and have several scratching posts throughout the house. Some with carpet, some with sisal rope, some have sleeping perches, and two are in front of windows that have bird feeders right outside so they can watch the birds. They're also of varying heights. Two almost reach the ceiling and are connected by a 1X4 plank that my husband attached. The key for our cats has been to keep them occupied and happy.
