It is the cat food I dont like, so I do two lots of washing up, mine and theirs (incidentally, theirs normally gets done first!!), different sponges - would be different washing up bowls if I had space for a spare one!! I never used to have issues when I only had 2 cats, but now there is so much that there wouldnt be space on hte draining board for us all. If I am low on time, theirs gets done and mine waits!! I have enough bowls for them all to have about 3 each, and I have more than I need for me too.
