Name changed🤪
Excuse the length of the post and also any errors as using my phone.
2 neighbours are currently having a argument over a incident that happened this morning.
Neighbour A let her children and her dog out to play this morning in to her own garden neighbour B’s cat was in their garden and got spooked by the kids and the dog. The cat has tried to climb the tree to get over the fence but somehow has managed to get caught. Cat stuck in tree with dog at the bottom barking madly at it. Neighbour A and B have both run out to garden as the noise from the cat and the dog were both very loud. B manages to get the cat untangled by leaning over fence on a chair. Cat obviously has injured its leg and was rushed to the emergency vets.
Now B has knocked on A’s door and said that the cats leg may be broken and its having x rays this afternoon etc she is waiting for a phone call from the vet she then said how would A be paying the bill? Would she pay her or go direct to the vet and pay the bill? 
A has stated that she is sorry that the cat has injured itself but she will not be paying as it was a accident and she can not see how she is at fault and has to pay for it.
B has gone mad and said her cat was spooked by her children and dog thats why he got stuck and was struggling to get away from a mad dog so it’s obvious she needs to pay!!
B said she will be back once the vet has phoned to let her know the amount and that if she isn’t prepared to pay she will be taking it to small claims court as it’s A’s fault her cat is injured.
A has asked my opinion as we are friends and whether she is being unreasonable. I think she is in the right and is not being unreasonable at all.
So why I sit and curtain twitch
What do Mumsnet think is A being unreasonable by not paying the bill?
