well on topic I've used a bowl with guinea pigs and changed a couple times a day was usually good enough. I preferred the bottle though. My rabbit only uses a bowl but his whole cage isn't covered by shavings.
What you need is a chew guard so they don't keep ruining the bottles. If you can't buy one it really wouldn't be to hard to make something.
Ont he barrowing. you find someone to lend you the money so you can find the money to use by finding someone to give it to you or by finding something to sell. You found a way to get the money so in a way you found the money.
I was a little scared to post in here though. To get that mad over someone suggesting to use a water bowl? If they knew you what might they do to you for using one yourself if they think it's that horrible?
There are water bottles all the time at one thrift store I go to. Just bleach them really good.
