Why Do Foxes Keep Going After Empty Milk Cartons Filled With Water?

[Treacle71]

After 4 pints of milk has finished, I wash out the plastic carton, fill it to the top with water, keep it standing by the back door, to keep to water plants/flowers in the garden. However, recently, the foxes have dragged these filled water cartons (4 pints in weight too) onto the lawn and chewed the handle and the water empties out onto the garden. This has happened three times now. I just wondered what could a filled carton with water be so appealing to the foxes? I’m going to have to stop leaving them outside now. My cat is also scared of foxes.

Perhaps they were desperate for water.

Foxes will play with anything. Maybe they can see refractions that attract them, the cubs will be exploring now they have abandoned the their dens.
I find plastic windmills, artificial flowers, teddy bears, little vases, trinkets in my garden that the foxes have helped themselves to from the graves and memorial gardens. People complain they are stolen or blame vandals but it’s mostly the foxes.
They will gnaw through my hosepipes if I leave them out
