Poop collecting

I let my birds come into the conservatory/utility room as we do enjoy each other's company. Me working on the books and they sleeping by the kitchen door, sometimes purring as they do

However, when they wake or get bored then they will wander outside leaving me some poop to get rid of.

I find the best way of getting this up is with an old envelope, from the recycling, rip it in half and one half in each hand push the two halves together and you got it!  Even the runny ones can be mostly got up this way, then a quick wipe with an anti back wipe and my wife would never know
