My cat jumped on my stomach 8 hours ago and now i have pain only in that area when especially if i move or laugh and it hurts when i touch it is it a bruise or something more serious?

Abdominal Pain: Abdominal muscle or rib muscle strain can occur after minor trauma. Localized pain at the site of initial trauma points to an abdominal wall injury. A minor muscle strain will likely improve within 24 to 48 hours. If the pain worsens, becomes generalized, or is accompanied by nausea vomiting, evaluation by a doctor would be appropriate.
