Something to calm her - ask your vet about Feliway. Feliway comes from the glands on the cat's face that they rub on things or people when they feel safe and affectionate.

It can be expensive, but it lasts a very long time.

Even with urine infections, cats start to think the litter box means pain. Try to retrain her gently, and give her lots of love.

I hope your baby gets well soon!
