We have had to start looking our cat in over night. This is partly due to roaming foxes and him getting into standoffs and partly due to him bringing in live animals at night/dawn (rats, mice and birds). Hes been fine for the last 2 weeks but last night he weed on our bath mat in the night. I feel really bad as he comes in at 10pm and i let him out at 7am so i thought he was fine with his business. Anyway we will have to reinstate a litter tray but how can I rid the smell in the meantime? I chucked the bath mat and washed the floor with water and bleach and it still smells!
