Two other things I would check is her gums and her kidneys. Lift her lip and check the color of her gums. If they are very pale, close to white, I would worry and maybe try to get her in to vet. And place your palms over her kidneys, alongside her spine between ribs and hips. If you feel significant heat or swelling, or if she seems tender or ouchy, time to see the vet. Maybe she just ate something she shouldn't and it will resolve quickly. One certainly hopes!
