ha i don't mean a credit card, i mean say you're vet bill comes to £100 will they let you pay 25 a month, then it won't be too bad on your mum and dad.
Maybe say to your mum and dad that if you don't take the piggie to the vet it could be in a lot of pain, and piggies hide their pain very well for it to be showing signs it could be very serious.
I am sure they would rather have a happy daughter than a very upset daughter. I'm not saying bribe your mum and dad here, by the way, but at 14 you can't be expected to pay. I'm sure your mum and dad will understand maybe ask them to take piggie to the vets as an early christmas present. I am sure you would rather your piggie be checked by a pet now than have a new toy at christmas but still have your piggie
