Hello Sara, Sorry to hear your family are not keen on cats, it sounds like you would really like one. Our cat has a bell on his collar, so I have a good idea where, he is, problem with that is, I was given a similar bell to put on my purse / handbag, so I could tell if some one was trying to steal it, needless to say it gets a bit confusing. It sounds like a really good exhibition you went to, with lots of useful information. Like you I've been thinking for a long time about having a guide dog but I'm still unsure about applying for one. Charlotte.
