Life Savior ECO, 5–10 kg is worth considering if best technical measured-fit option for unusually large cats is your priority in cat-specific and measured-fit flotation aids for supervised boating, docks, and calm-water introductions. Check fit, current price, and retailer availability before buying.
Skip it if officially designed for dogs and starts at 5 kg, excluding most small and average cats is a dealbreaker, or if your pet needs a different fit, size range, or retailer return policy.
Compare related options, then check current details with the retailer.

O'Brien
O'Brien's XS chart reaches pets up to fifteen pounds with a 13–20 inch girth, and the vest has a top zip, adjustable neck buckle, two ladder locks, reflective nylon handle, and leash ring. The price, current direct stock, and nine retailer reviews provide better commercial evidence than several mixed-pet entries. O'Brien itself describes the product for dogs, however, so a matching cat weight never proves a safe neck, shoulder, or torso fit and this option belongs only after cat-labeled models fail measured dry fitting.

Grabner
Grabner's Austrian-made CAT + DOG vest explicitly includes cats and gives size S a body-weight ceiling of ten kilograms and chest limit of 55 centimeters. A 250-gram nylon shell, layered PE plate foam, three-way webbing with four buckles, handle, and D-ring make it more substantial than the cheapest mixed-pet vest. The chart gives maximums rather than minimum-to-maximum ranges, there is no numeric review evidence, and the bulky multi-buckle shape still needs a complete feline dry-fit test.

LALIZAS
LALIZAS code 20020 is explicitly suitable for dogs and cats under eight kilograms with a published 25–48 centimeter chest range. Foam construction, perimeter straps, and a strong lifting handle create a straightforward marine design, and the Irish retailer had current stock at a moderate price. It provides no cat-specific neck measurement, the retailer review evidence is minimal, and its strap-forward form requires careful checks for rubbing, rotation, and backward escape.

Vibrant Life
Vibrant Life is the easiest low-cost US checkout in the comparison and explicitly labels the extra-small vest for cats and dogs from five to ten pounds. Adjustable neck and chest straps, reflective trim, breathable mesh, a top handle, and D-ring cover the expected basics, while 56 ratings provide more public evidence than the cat-specific models. The broad mixed-pet shape may not control rotation or shoulder escape on every cat, so dry movement checks matter more than the low price or star score.

Besto
Besto Deluxe is a lower-cost cat-specific option with 0–3, 3–7, and 7–10 kilogram bands, a lifting handle, D-ring, and three buckle points around the body. The price and clear cat label make it attractive for a cautious first setup, and four full product photos plus a verified alternate rendition document the construction. It lacks meaningful public reviews, has less detailed fit guidance than the first two choices, and the current purchase path is a Dutch marine retailer.

Baltic
Baltic Maja combines a cat-specific neck opening, broad belly strap, D-ring, recovery handle, reflectors, and three weight bands from zero to ten kilograms. It is substantially less expensive than SurferCat, carries a five-year Baltic warranty, and has current European retail stock. The fixed weight bands still do not replace chest and movement checks, the public review sample is only two, and the verified purchase path is European rather than a current US retailer.
