it depends on what you’re looking for and where you’re looking! i bought mine from a local shop in town for i think £8 and i’ve seen some really fancy ones in a giant garden/pets/etc store that were really pretty but super expensive, maybe £30…

there’s lots of them on ebay but the prices vary and some of them are really expensive.. a foldable one i really wanted was maybe £25 but it was too much for me personally,, you just have to look around, try ebay and amazon! i recommend getting an adjustable height one rather than one of the wooden ones too :0
