Best window perch hardware for Ragamuffin cats

Window perches are honestly one of the best enrichment additions you can make for an indoor cat — they provide natural stimulation from birds, passing movement, and sunlight, and a well-placed perch genuinely improves day-to-day welfare. The two things that matter most are suction cup strength and a weight rating that suits your cat. Since you're going the DIY route, the hardware you choose is everything. How heavy is your Ragamuffin, what kind of windows do you have — smooth double-glazed, textured, or older single-pane — and is this perch for just the one cat?

9kg is a solid Ragamuffin — they do run large. Good news is smooth double-glazed is the best possible surface for suction cups, so you have real options. Before I point you at specific hardware, are you planning to build a full shelf with a wooden board, or are you looking for a ready-made bracket set you just bolt a cushion or board onto? And roughly what size perch are you thinking — something like 40–50cm wide, or larger?

Perfect approach — cutting your own board gives you exactly the size he needs and works out much cheaper than buying a finished perch. For the brackets, I'd go with the MUYG Heavy Duty Suction Cup Shelf Brackets. They're sold as a set of four on Amazon UK, each bracket is rated to hold significant load on smooth glass, and the combined rating comfortably covers a 9kg cat plus the weight of a solid shelf board. The cups are large-diameter — around 8cm — which is what gives them reliable grip on double-glazed units. At under £20 for the set they're genuinely good value for DIY use. Just make sure you clean the glass with isopropyl alcohol before pressing them on, press and twist firmly, and let them sit for 30 minutes before loading the shelf. That curing time is the step most people skip and then wonder why the thing drops.

Go with 18mm MDF or 18mm plywood — MDF is cheaper and perfectly fine if you're going to cover it with carpet or fleece, plywood is lighter and holds screws better if you want to attach the brackets through the board from above. For a 50x30cm shelf carrying a 9kg cat, 18mm is the sweet spot between strength and not adding unnecessary weight. On the safety cord — yes, absolutely add one. A simple paracord loop from a small hook screwed into the window frame, looped loosely around the bracket post, means if a cup ever loses grip the shelf drops an inch rather than falling completely. It takes five minutes and costs almost nothing. For a cat that size it's just sensible.

That'll make a great perch for him — Ragamuffins really do love a long lounge in the sun once they find a spot they trust. One last tip: put the perch at a height where he can step onto it from a nearby surface rather than having to jump straight up. At 9kg, making it easy to access means he'll actually use it consistently rather than deciding it's too much effort.
