This is the most substantial cover in the roundup at a full 4mm of acrylic — noticeably stiffer than the 3mm alternatives. The 19.5″ length can swallow a full-size mechanical gaming keyboard with room to spare, and the 2″ height gives even a large cat enough interior space to sit without her paws pressing directly onto the keycaps.

Four corner cut-outs allow the cover to slide over keyboard cords without bending or stressing the acrylic. The edges are rounded and polished, with no raw cut marks that could catch on a cat’s claws or scratch your desk surface. It also doubles as a keyboard riser if your board sits too low — though the manufacturer notes that is not the primary use.

Owners report that cats will happily sit on this shield, and the acrylic does not flex or squeak under a 12‑pound cat. The 4mm build means it is heavier (and more expensive) than budget slabs, but for permanent pet protection on a full‑size board, this is the set‑and‑forget solution.

This is not a traditional keyboard cover — it is a clear acrylic monitor riser that doubles as a pet shield. The 4″ height creates a wide tunnel underneath where you can slide your keyboard, while the top surface acts as a flat, sturdy platform. Rated for 50 pounds, it supports a monitor, laptop, or even a large cat without any flex.

The 100% Class‑A acrylic build is polished to a crystal‑clear finish that matches modern desk setups. It arrives fully assembled (no screwing or clipping), and comes with a microfiber cloth for wiping away paw prints. Because the keyboard sits under the stand rather than under a lid, cat access to the keys is physically blocked by the riser’s bulk.

It is a smart solution for anyone who wants to elevate a monitor while also creating a physical cat barrier — two functions in one piece of furniture. Just measure your keyboard height first: the 4″ clearance accommodates most low-profile mechanical boards, but a tall keyboard with high-profile keycaps may not slide underneath cleanly.

Engineered specifically for the Redragon K556 (104‑key) layout, this half‑covered lid uses a TPU acrylic blend rather than standard PMMA. The internal space measures 16.9″ x 4.7″ x 0.6″, which means it sits close to the keycaps — a narrow profile that keeps the board low and stable while still blocking cat hair, dust, and liquid splashes.

The bulge design on both sides of the lid makes it easy to lift off one-handed, and the transparent panel does not dim the keyboard’s backlighting at all. Because it is a half‑cover (only the top surface is protected, not the sides), it works best for cats that step or lie on top rather than ones that try to squeeze a paw underneath.

Customer feedback highlights the precise cut for the K556 — no overhang or wiggle. The TPU material is slightly more flexible than rigid acrylic, so it absorbs minor impacts without cracking. The manufacturer backs it with a lifetime warranty, which signals confidence in the build quality for daily pet use.

The KC04 uses a full‑surface hot‑bending technique that physically forms the acrylic into a single seamless shape — no glued corners or separate side panels. The result is a rigid, one‑piece enclosure with rounded edges that feel smooth to the touch. It fits standard 98‑key mechanical boards, with internal dimensions of 17.4″ x 6.5″ x 1.89″.

Waterproof and dustproof ratings are standard here, but the hot‑bent construction gives it extra structural integrity compared to flat sheets that are simply glued. The 1.89″ height provides enough clearance for most OEM‑profile keycaps, and the transparent finish shows off any under‑glow or backlighting without distortion.

The manufacturer explicitly states that the cover is designed for keyboards at least 1″ smaller than the cover’s dimensions — so a full‑size 104‑key board will not fit. For a standard TKL or compact mechanical, this is a clean, well‑made lid that stays put under a cat’s weight because the walls hold the shape firmly.

The KiiBoom cover is designed for 75%, 96%, and 98% keyboard layouts — compact form factors that do not need a massive lid. At only 12.6″ x 5.3″ x 0.78″ and weighing just 0.28 kg, it is the lightest and most portable option in the list. The 90‑degree heat‑bending technique ensures precise corners that match the shape of smaller boards without excess overhang.

The acrylic is high‑grade and crystal clear, with each edge polished to a smooth finish. While the 0.78″ height is lower than most cat protectors, it still creates a physical barrier that prevents direct paw contact with the keycaps. For owners of compact mechanical keyboards who need a simple, low‑profile shield, this covers the basics without taking up extra desk real estate.

It is important to note that the thin 0.78″ walls mean a determined cat might be able to push the cover off or slide it around if the board is lightweight. The cover works best as a dust and hair barrier for cats that tend to step rather than shove. For the price, it is an incredibly well‑finished lid that delivers the core function without frills.
