The cat may start having tremors and having convulsions. In some cats, their body may become stuff. They may lie with their limbs stiff and rigid.
If the cat received poor nutrition during or after the pregnancy, she is at a higher risk for eclampsia. Cats who carry and give birth to large litters are most at risk.
The vet may want to know details about your cat’s diet during and after pregnancy and any supplements she’s been given.
Magnesium levels may also be checked.
Vitamin D may also be given to help the cat absorb the calcium.
This will be given while at the vet to stabilize the cat before they are given calcium supplements.
If the vet thinks the mother shouldn’t nurse anymore, they will recommend weaning the kittens.
Provide the mother cat with a good quality kitten food, as this is more energy dense and has a higher level of calcium than regular cat food. Don’t give the cat calcium supplements without a vet’s approval. Calcium supplements during pregnancy can mess up her ability to absorb it, which can lead to eclampsia. Calcium supplements after pregnancy can also be dangerous.
