I now use either face clothes or small hand towels for poo jobs!
I have a towel on the floor (cant use the station now as she tries to get off)
then squirt her butt all over with the water sprayer and give it a good wipe with the cloth, then dry it with the bit of towel she is laying on. Then hang the towel up for next time. You can buy big batches of hand towels on ebay for not much money
