cos feeding strays not only dirties the common areas, it encourages flies and pest and the further breeding of yet more strays ! ....
if one's that enamoured about cats, adopt the strays, take them in, or bring them to the SPCA, don't scatter packets of rice around void decks and around rubbish chutes and scuttle off, leaving half eaten bits of cat food and rice lying around rotting for the banglas to be cleaned up ! ....
there was this ah pek that used to do that around my neighbourhood, who'd go around feeding strays with newspaper wrapped bits of rice and fish, creating a huge mess every time ! ... and the cat population exploded ! ... best part ... he doesn't live in my estate, so he doesn't have to deal with the consequences ! ...
