Oh Lut, I sympathize with you fully. When Annie and Emma were in my yard before I completely adopted them - it was clear both were going into heat.

I lured them into my home and called the vet. They couldn't take them until Monday - and this was only Thursday. By the time I got them to the vets on Monday - I had an amazing weekend - and poor Rascal was just beside himself.

If you cannot find another vet immediately - and I sure hope that you can - I would just try to keep her separate from the other kitties and play soft music - for YOU!!
