Your cat sounds very young and playful if it is pouncing around at things! My 2 cats are 9 years old and I've had no problems at all with the baby. As soon as we decided which room was going to be the baby's room, we banned the cats from there. They haven't shown one bit of interest in DS or his stuff. They've never jumped in the cot whether he's been in there or not. They keep their distance! Now that DS is walking around, he follows them and they just run and hide under the bed or behind the couch.

I wouldn't be so quick to give the cat away just yet. Maybe wait and see how it reacts when you bring the baby home. Keep the distance between the baby and the cat and you should be fine.
