My cats have got scrathing posts, cat gyms and scratch mats, but Milo still swings on the curtains. They are all litter trained.
Cats all have individual personality's, some may be quite and subuded, others may race around like a demented chicken (my lot!!)
Older cats tend to be a little quieter than kittens.
People think cats are easy to look after, they're not, they need a lot of care and attention, and LOTS of cuddles, however in my opinion they are totally worth it xx
