30 Cat Warning Signs Owners Had To Put Up For One Reason Or Another

But we could all probably agree that no other house pet can do it better (or worse) than cats. It’s no secret that felines are infamous for being indifferent, feisty and sly. Best of all?

According to certified cat behavior consultant Ingrid Johnson, it’s actually possible to train them to use a leash or harness. You may also simply use a stroller to take your furry friend for a walk. Johnson also suggests “catifying” your home to meet the needs of your pet. For instance, you can install a screen on your porch or even build a catio. “Bringing the outdoors in” is another tip that the expert recommends.


“Grow cat grass, bring in dried leaves, snow, branches, pinecones, allow them to experience the seasons and the sights and scents of the outdoors in a positive way.”
