A word on wee this morning. I had an email in from a man who needed to remove a puddle of cats wee from his duvet. Nice! There are lots of great odour removal products on the market, but my advice would be to avoid using anything with ammonia in it. Urine contains ammonia and adding product containing yet more ammonia will only reinforce the smell and encourage kitty back to re-mark in the same place. Baking soda, which is bicarbonate of soda, can be very effective at removing urine from fabrics such as bedding and other washable materials. Add 1 pound of baking soda along with your detergent and wash with cold water. You need to wash carpets, bedding and so on in cold water, rather than hot because hot water will bake and set the odour into the fibres of the material. Baking soda naturally absorbs odours and discourages bacterial growth, so it is certainly worth trying. Good luck!
