We’ve had a little (1ftx3ft) greenhouse in our garden for about five years now – it started off as an actual greenhouse for growing things in but quickly became the cats’ favourite hang-out and the winter home of the local stray cat, so we dropped the growing things pretence and it’s now kitted out with old sofa cushions for the ultimate cat luxury.
It’s a simple – cheap – thing: hollow metal tubes and two shelves, covered by a shaped plastic sheet, with a zipped door flap at the front. The main problem we’ve had is when one cat is in the greenhouse, it’s not uncommon for a second cat to sleep on the roof – and under the heat of the sun/weight of the cat, the roof sags and eventually rips. That’s happened twice now and we’ve repaired it for as long as possible, then ordered new covers off the internetz – still not ideal though.
I’ve looked into buying little glass/solid plastic paned ones but they’re pretty rare compared to large ones and seem really expensive for the size of them. We’ve not got room for a big greenhouse but it would be great to make one that could be used by both the cats and our growing needs.
I know some people make them with old windows and they’ll depend on exactly what type of windows are at hand but anyone got any suggestions/advice? What other types of materials could I use? Does it have to be clear-clear or is reasonably translucent enough? What shape would be best – square? sloped roof? round? polytunnel-ish? biodome?
