In a similar situation to Spy38W's friend, my old flat mate went on the piss one night and brought back this white persian cat that she found on her way home, I remember this very vividly as she woke me up at 3am whilst I was in my bed, she was totally wreaked and decided to let the cat stay over for the rest of the night, but my other cat loving flat mate would have something else to say to her about the fact that she had nicked this cat, so o' pissed one, took the cat collar off so as she could pretent is was a stray?? And maybe eventually keep it?? I have not idea! Like we were going to keep it! Anyway, the cat was apparently returned to the wilderness the next morning and everything was cool.... ...until I found the collar on the heater the next again day... then, huge posters started appearing around our street and the neighbouring one. These things were laminated full colour pictures of the poor cat plus a long winded saga of the cats life of domestic triumphs and failures. One was even placed right outside the enterance to my flat. Boy did I feel guilty and It wasn't even me!!! Now it has become manditory to give ribbings to my old flat mate for any episode involving cats and large posters. And now several years on, see has bought a cat of her own in order to append what mistakes she has made in the past to any cats she came accross and named it after her favorite beer!!!! Miller!!!
