Cat tower or climbing frame (Moreton CH46)

Hi we’re looking for an activity cat climbing post we th seat bits etc if anyone has one their cat doesn’t use .. we’ve recently lost puss cats dad & we keep buying her things to try and keep her entertained but she turns her nose up so don’t want to waste money if she won’t use it.if we get one and she doesn’t like it we’ll donate it to a good cat charity so it won’t be wasted.if anyone has anything suitable we would be really grateful .many thanks.
