I foster unwanted cats/ kittens and as cat owners know mornings can be very rowdy. I have a 5-6 month old kitten, she can get extremely wild in the mornings. She is just running all over the house from top to bottem. Well this morning she was in her usual craziness and she jumped on the banister on the second floor. I guess she lost her balance cuz she fell and there are steps and the first floor landing. All hard wood. After i heard the fall i ran to see what happenend cuz all the cats just scattered. she ran and hid in the basement. When i went to check her she growled at me . This is not her nature at all...she sleeps on my neck and purrs and kisses me all night long. Her lil nose was bleedin, not very much though. A this point she is lettin me know she is upset and leave her alone. I took her upstairs and laid her on my bed. I keep checkin her every few min. She is sleepin. I woke her up and she let me feel her from head to toe to see if anything was broken. I made her follow my fingers with her eyes,she seems ok that way. Just tired right now.I am going to treat her as if she has a concussion and not let her go into a deep sleep. Any other ideas?? She is purring now, just seems tired....
