CatWorldly cat gear measurement checklist - Measure the cat's length, height, weight and mobility before buying fixed-size gear. - Carrier: cat should be able to stand, turn around and lie down; floor and latch must be secure. - Litter box: longer than the cat from nose to tail base; entry should match age and mobility. - Scratcher: tall or long enough for a full stretch; base should not wobble. - Cat tree: platforms must match cat size and confidence; anchor tall structures when possible. - Feeder or fountain: food and water-contact parts should be removable and easy to clean. - Label the recommendation honestly: research-based comparison, editorial selection, hands-on tested or specification guide. - Add affiliate disclosure near product links if affiliate links are used.
