My cat has attacked a bird I think its broken its leg its lying on its side with its leg sticking out its breathing and if you take the towel off the box we have put it in it looks in our direction there are no vets open and when I got through to a 24 hour emergency animal centre they told me to phone the rspca but I couldint get through they said that they could pick the bird up but they said it would cost us 50 pounds and we cant afford that and all the vets are closed please help what do I do I don't want the bird to die
