Please have belle spayed. There are many groups that will have clinics at a lower cost. Why your shelter did not offer that, I don't know. The fact the first litter of 5 died is not good. Has your cat been seen by a vet? Sadly the cat and dog population is out of control. Many animals are put to sleep each year while others live a horrible life, cold, sick, hungry, injured, and not loved. The shelters are filled with animals that no one wants, why breed even more? Please be a responsible pet owner and have them spayed, or neutered.
