I'm a little concerned about my 4 1/2 month old kitty. I've had her about 5 weeks now and she's happy and otherwise healthy, but whenever she goes poop, her rectum is rather bloody. Her stool does not have blood in it.
She eats well (dry food) and drinks water (almost excessively). She comes running whenever I turn on a faucet and cries to have the tub turned on so she can have a drink and/or play in it. She plays well with her new brother and sister. The only thing that I can see maybe out of the ordinary is that I can't keep her from eating the adult food from her older cat siblings, which she ocassionally does. I'm feeding her Iams Kitten Food, because it's the only thing she will eat, I went through three brands already before she would actually eat the kitten food.
She doesn't sound like she's struggling when she goes (I can't see her the litter boxes are covered).
Any ideas?
