Great Question! Yes, it will be able to keep your cat on your balcony. We have several happy customers who rave about how they are able to keep their pets on their apartment balcony thanks to the deck netting.

Yes, very easy to cut!

The holes in the Outdoor Safety Netting are 1/2-inch squares.

This product is typically used to close the gaps in posts on decks and patios. Whether this would work on your carport would depend on the size/weight of the dog, ability to jump/climb, etc. You may need a more heavy-duty option than this. Hope this helps!

Thanks for your question! Cardinal Gates offers the Stairway Special Outdoor Gate (Search #1455702 on PETCO.com). Ideal for decks and patios, it's the best gate out there for use outside. Aluminum construction and stainless steel hardware mean excellent durability against the elements. The bar spacing is 2.5 inches so be sure your Boston Terrier can't pass through that space. The gate features an adjustable with from 27" to 42.5". You can span the 105" you need by adding additional width extensions, sold separately. There is a 21.75" extension (Search #1455753 on PETCO.com). Each extension is fixed-width. To span 105", set the gate width at 39.75" then add three (3) 21.75" extensions to reach 105". NOTE: The entire width will open/close which is a bit much. You can make the extensions stationary using the Cardinal Gates T-bar and hinge. These are available directly from us as the manufacturer. It is a specialized accessory that PETCO.com does not currently sell. See photo below. Although this photo is indoors, you can see how it works. The extensions to the left of the baby are stationary. The gate portion is the 2 panels on the right. Also note, the T-bar is steel for strength. It will rust outdoors so you will need to treat it with rustoleum or a similar anti-rust product. Please call with questions but this is our one solution that will work for your space! Enjoy your Outdoor Gate!

Not unless you have something to tie it to, because it is only netting. There is no canvas or vinyl trim and no grommets, so it would be flimsy enough for a pet to get under or around it.

I sent one answer, but am adding to it, because I don't see it posted yet. I double checked the item description and am even more displeased that I indicated in my item feedback. It may fit your patio because it is 16 feet long by 3 feet high. However, the hardware indicated in the item description is merely black plastic electrical type straps. They will last longer that the netting, which is also not as thick as it looks in the item picture. I wouldn't buy it again.
