BH and Ruty, I have read this thread in a different light to you entirely.
I don't think anyone is advocating irresponsible pet ownership, (I quickly re-read the thread, but couldn't find any mention of forgetting to feed an animal, so can't comment on that) but unfortunately accidents do happen sometimes.
The OP was genuinely asking for advice re the situation, and others were telling of their experiences.
In my case I was recounting something that happened to my pet hamster. I'm sad it died, but looking back I do find black humour in the situation.
I'm sure no-one meant to cause offence.
Kitty, we've got two guinea pigs who are gorgeous. They are very friendly, love being handled, and are larger than gerbils, so easier for little ones to care for IMO.
They are so sweet, and love to play on the 'assault course' the children have made for them in their run.
Perhaps they would be a good idea as a next pet?
