If the blood appears to be inside the eye itself, this is called hyphema - the most common cause is trauma, but it can also be caused by a severe eye infection, a bleeding disorder, or certain systemic illnesses such as lymphoma or FIP. If you think the blood may be trauma-related, I would recommend having her examined by a vet as soon as you can - eyes are very delicate, and many conditions can lead to vision loss or permanent damage if they are not treated promptly.
