Our Verdict

Petivity takes a fundamentally different approach: no wearable at all. The sensor slides under your cat's existing litter box and tracks weight changes and litter box visit patterns over time. This is significant because cats are notoriously resistant to wearing anything, and gradual weight loss is one of the earliest signs of kidney disease, diabetes, and hyperthyroidism. For collar-resistant cats, this captures genuinely valuable data that would otherwise be invisible.

Zero wearable — ideal for cats who refuse collars

Cons

Cats only — no dog support
Limited data scope: weight and litter visits only
Less useful if cats use multiple litter boxes
No heart rate, temperature, or GPS tracking
Can't distinguish cats of very similar weight reliably
