We have a cat tree/carpeted scratching post, but the cats use that more as a playground then anything. They prefer the corrugated cardboard scratchers the most! Or random boxes whenever they're available! I think we've been lucky and our cats arent furniture scratchers, but Roly likes to claw at the wall by our back door. We remodeled last year and have french doors leading on to a balcony. Hubby has yet to put the trim up, and Roly likes to dig his nails into the drywall there... Amazingly though, there are no scratches Go figure. I catch him and stop him from doing it all the time. Maybe it's because the wall is textured that I am not seeing the scratches... or maybe he's just puncturing it... who knows. Eventually the trim will go up... if I can light a fire under hubby long enough... and hopefully then Roly will leave it alone!
We had a foster mom dig at the carpet in our bedroom once. It's still bare in a spot, but now I have a throw rug there in case any other fosters try and get the same idea.
My mom adopted a cat and was having trouble with her climbing the curtains. I suggested a window seat and a cardboard scratcher (she already had a post) and she hasnt had any instances since. Now her cat is content to sit on the window perch and leaves the curtains alone!
Another place that Roly scratches is in his litter box. I recently switched over to a big rubbermaid container... when he is done, he scratches the heck out of the lid. I dont know what he thinks he's burying, but he seems to dig on forever
None of my cats are really big on kneading... but our most current foster, Digit/Snickers, is a huge kneader. I think it's cute... except for when she catches you with one of her many claws!
I trim the kitties nails regularly, but have really given up on the resident cats. They dont really use their claws much so I dont find a big need for it. Gotta love a soft paw! But the kittens, they will be used to it when they go on to their forever homes...
