If you're like me and have spent far too much time studying why your garden has a pungent smell of cat urine, the source might surprise you (and you can fix it).
First things first: There is always the possibility that the cat urine that you smell in your yard or that blows through your window is actually cat urine. Especially if you have domestic cats, there may be outdoor cats that mark your home. But if the smell is not just a stinging moment, but an inferior smell of cat urine that persists in spring and summer, then surely you can stop blaming the random stray dog for it.
Instead, you should accuse the boxwoods. While there are a variety of ornamental trees, shrubs and plants that have unpleasant odors, the boxwood is the likely culprit in your garden. The plant not only smells of sharp and stubborn cat urine, but also in much of America, Europe and beyond, box trees are virtually ubiquitous in landscaping. When I went for a walk with the dog the other evening, I made a rough list of the houses in my neighborhood, in the courtyard of which boxwood trees were planted. Over 90% of them did ̵
It's a shame because box trees offer beautiful landscaping. They have a rich, glossy green, are easy to shape, from simple balls and cubes to complex topiars, and it's hard to beat them for the relatively inexpensive visual weight they add to your landscaping. One can hardly imagine an English garden without boxwood.
Oh, I'm going to rip mine out because I do not want to spend another year thinking, every time I open the windows, "Why does it smell like that? Similar to cat pee here?
In conclusion, I would like to warn you: Despite the claim of landscape designers and garden shops that there are odorless or low-odor box trees, there are none. The box trees planted in front of my windows are specially a variety, Buxus microphylla var. Japonica popularly called Winter Gem Boxwood, because it is so lively in winter. It is often cited along with the Wintergreen variety as the perfect boxwood wood to avoid the Katzenuringeruchs.
I can assure you that this is not the case.
