you probably just see it more where you live as you have a higher turnover of new tenants than normal areas would where people dont move about so much.
EXACTLY! You've made my point for me. I would have loved to have a cat when I was at uni, and it's the only time in my life I haven't been with a moggy, but I knew that I would spend a few years moving at the end of the academic year, doing summer jobs at holiday camps (no, I wasn't a redcoat, I shovelled chips in a 'self service' cafe, very boring but gave me some cash in the second year!).
This area didn't have a high turnover before students arrived, as it was all owner-occupied and the residents moved every five years, or often less (the guy next door had been there for over 40years, he's past on now, and it's a student house).
I did make the point that any student on Purrs would be of the responsible variety, otherwise you wouldn't be on this forum. The mature students are an exception too. One of my friends, Rebekah, was a mature student and had five (now four, one died of hyperthyroidism) cats at the time; but she has her own house, stability and had the cats before she decided to go to uni (she now has an M.Phil), she was in her 40's when she began her course, so had some sense of committment, having raised two, now adult, daughters.
But 18 year olds, feeling homesick, never before having to even pay utility bills, never mind VET bills, may not fully appreciate the committment they enter into when they take a cat, and I'm sure that there are a good percentage who don't care. I would put this down to their age and the crazy social life studenthood allows (been there, got the tee-shirt; and it's no place for a cat).
This isn't directed at mature students, but at 18 year olds who have just left the security and boundaries of home. Cats can seem like cuddly companions to get you through the first two terms of homesickness; then you make friends, go out, have work to do ........and oh yes, the cat.....who cares about the cat!
