Oh ffs, the only bin in this house is in the kitchen. Everything else gets taken down to the kitchen bin/emptied into it. I then have a "recycling" store under the stairs, and filled up "rubbish" bags in the shed until i can be arsed to take it to the waste centre (am not in UK) The kitchen bin has a liner which is ultimately put into a black sack - in the shed, and other kitchen liner bin emptying will join it. WTF is lining bins with carrier bags about? Do you go putting food and other "sticky" or liquid waste into bins all around the house?
(Am not very serious, just find this bin snobbery a bit silly so answering in kind)
Geri, if all you have is a rug, throw it outside in the morning, and see if the house still smells when you come back from work tomorrow. If it does, then perhaps your cats have left you a dead "present" somewhere that you're only just noticing after having got rid of icky bin goo.
