my sister gave my family an adult male cat as shes moving soon hes real relaxed and he just came downstairs and walked near my tanks and my texas started going crazy so i sent the cat out. but it seems that he ran into the tank sides a coule times. He has a big bruise on his forehead and it looks like he messed his eye up a bit and now hes just sort of treading on his side near the top. PLease what should i do im freaking now.
