Ulla, a one-year-old tabby cat, was rescued off the streets and taken to a shelter. After a couple of weeks, staff noticed a bulge in her belly that was getting bigger. They took her for an ultrasound at the vet and discovered that she was pregnant. Ulla seemed shocked and even let out a scream when she saw the ultrasound screen. It was believed that she was carrying four to five kittens. Ulla has now found a forever home, and once her kittens are old enough, they will be put up for adoption.
