Pet Safe Invisible grille

Any pet owner can tell you how important it is to keep their pet safe, but not everyone knows how to do that. This post hopes to bring light on this topic for Invisible grille (IVG).

Invisible grille provides unblocked view of the window opening due to it’s thin tightened cables. Each cable has a fixed gap distance with the next and typically the standards are 2, 3 or 4 inches apart. 3 to 4 inches is typically alright for young children. 2 inches is normally used for home with pets. For cats, it is recommended to go for 1.5 inch gap. Or 1.3 inch if you have kittens.

Cautionary note for Cat Owners

Do note that, Invisible grilles with a smaller gap is better at cat-proofing adult cats instead of kittens. Pet owners may need some sort of a mesh with smaller gaps to protect the kittens until they mature.

Do make sure stiffeners for the invisible grilles are installed. They can be quite flexible and as they loosen over time, it is important to tighten invisible grilles every couple of years.

Comparing options

Invisible grille is a good option if you’re looking for an unblock view, but that is not the only one.

Other options like Pet safe aluminum grille, Mesh or Nets can be effective as well. However, it does partially block the outside view and tend to make the space look smaller than it is.

What to consider for Pet Safe Invisible grille before buying?

  • Membrane Material — Cable’s membrane is to protect the cable against any external factors. They are all made out of some plastic variants and will weaken over time (due to Sun’s UV exposure). Hence it is recommended to get a good membrane if the balcony/window is constantly exposed to strong sun especially if your pets are able to reach and potentially bite it. Currently common in the market are 2 types of material used for the membrane: Nylon, Teflon.
  • Warranty Type & Period — Warranty ideally should cover on the cable against rust and workmanship related issues (e.g. loosening of the cables). This is typically around 5 years. The other warranty should be with the cable’s membrane against peeling or wear and tear that deems abnormal (typically membrane should last around 3 years). This warranty is provided for around 3 years.
