ProtectaPet® Cat Fence Extension Post and Bracket

Neighbourhood cats do have the physical ability to jump into your garden from on top of your fence. However, most cats will see that there is no exit from the garden and choose not to enter. Our customers report that neighbour’s cats tend to choose not to enter their gardens because they cannot see an escape. If you are leaving your garden unsupervised while going on holiday for instance, it is a good idea to leave an escape route for any cats that might enter (a wheelie bin against the fence is a good solution).

ProtectaPet cannot offer planning advice because regulations vary by area. Generally speaking, cat fencing solutions are not permanent structures and are below 2m in height. Please keep in mind that planning regulations in front gardens and in conservation areas are more restrictive. We advise you to contact your local authority for advice specific to your circumstances.

If a tree trunk or branch is within 6ft/1.8m of the boundary, it will require a cat barrier. Depending on the girth of the trunk and the proximity to the boundary, there are multiple options. Review our handy blog for an overview.

Where a shed, summerhouse or garden office falls within 1.8m/6ft of your boundary, you'll need to continue the barrier around it. Whether your shed is timber or aluminium, close to the boundary or inset from the boundary, will determine which brackets you will require. Generally, you will require at least one external corner bracket. Read our handy guide to sheds for more information.

If you have a mature garden with lots of plants, the cats will absolutely love the enrichment it offers. In order to install the fence barrier, you may need to undertake some pruning and trimming. For example, you'll generally need the top 1ft/30cm of your fence or wall to be clear of plant growth. For more detailed guidance on preparing your garden, please see our blog.

If you have a pre-existing gate - whether it is made of timber, steel or composite - the best way to cat proof it is to add a brace above the gate and fix the barrier to the brace so that the gate can move independantly. For the gate brace, you can source 3 x 2" timber. Where it fits in with the aesthetic, our Installation Engineers use black coated steel-tube. For more information on cat proofing gates, please read our blog,

We suggest keeping a minimum of 6ft/1.8m between the highest leap point and the cat barrier. Window sills can create leap points for cats when they are located next to the perimeter. We suggest building a window sill canopy and you can read further guidance on this here.

Most fence panels are 1.8m wide (plus fence post width) so our kits are based on 2m intervals. If your fence panels are wider or you are attaching the brackets to a wall, we recommend that you space the brackets evenly up to a maximum of 3m intervals.
