It really annoys me how some people come up with all sorts of excuses to give up their cats. When you offer them solutions though, they just ignore your suggestions (without even going through them) and keep insisting that they have to give their cat up. I do know responsible people who had to look for new homes as a last resort, but this was their absolute last resort and they tried everything else first. They were also in the minority.
People treat cats like disposable - when something else better comes along, they just get rid of it. It's like the ads I see in the papers sometimes - 'Giving up hobby. Selling dog/cat/hamster/fish".
I was just saying to Michelle that people treat cats like furniture - so easy to give away. Then we both realised some people treat their furniture better than they do their cats.
