Yep it was the goats again. Give up all hope for your mum....
Straight from Wikopedia this informing snippet.
This puts goats with animals such as rabbits and other vermin....


A goat is said to be truly useful both when alive and dead, ( I like this
bit, so it doesn't matter if you kill them(grin!)) providing meat and milk
while the skin provides hide. A charity is involved in providing goats to
impoverished people in Africa. The main reason cited was that goats are
easier to manage than cattle and have multiple uses.

Feeding goats

Goats are reputed to be willing to eat almost anything. Many farmers use
inexpensive (i.e. not purebred) goats for brush control, leading to the
use of the term "brush goats."

'Bush Goats' in oz!!

Goats do not actually consume garbage, tin cans, or clothing, although
they will occasionally eat items made primarily of plant material, which
can include wood. Their reputation for doing so is most likely due to
their intensely inquisitive and intelligent natu they will explore
anything new or unfamiliar in their surroundings. They do so primarily
with their prehensile upper lip and tongue. This is why they investigate
clothes and sometimes washing powder boxes by nibbling at them.


Sure, maybe YOUR goats didn't, Wikipedia genius.... I used to get holes
chewed in my clothes (not explored or nibbled, but masticated), not to
mention shoes.....and we had one that broke in, ate a pot full of jam that
was cooling, and subsequently died. Mum was not pleased.....no jam, no goat.
Dad wasn't all that worried though for some reason....
