Iron-deficiency anemia, the most common form of anemia, is a decrease in the number of red blood cells caused by too little iron. Without sufficient iron, your body can't produce enough hemoglobin, a substance in red blood cells that makes it possible for them to carry oxygen to the body's tissues.ron in plant foods such as lentils, beans, and spinach is nonheme iron. This is the form of iron added to iron-enriched and iron-fortified foods. Our bodies are less efficient at absorbing nonheme iron, but most dietary iron is nonheme iron. 1  1.
Newborn kittens are tiny and cute, but they grow up startlingly quickly. Many female kittens actually will have their first heats as young as 4 months. To spare your sweet little furball any possibility of pregnancy so young, you can consider spaying as early as 8 weeks old.
I don't think that a ten week old kitten is at risk for pregnancy, but you should plan to have her spayed as soon as she is old enough for your vet to do the procedure, it will save you a lot of sleepless nights (cats in heat can, and will, cry all night long) and unwanted kittens.
