Coco surveys the world from the top of the bunk bed
Cats need high places. Perhaps to preserve their natural superiority, perhaps to see danger coming, perhaps so that they can watch without being seen ... who knows?
All I know is that cats who don't have high perches or hiding holes can show signs of stress. Every day I see them with bladder inflammation, excessive grooming, urine marking and other signs of feline stress.
Does your cat have a hidey hole, high or low?
