Kittens are blind at birth, but the touch receptors in their noses are already developed. Rubbing noses with their mother may help them feel secure. My cat likes to touch its nose to my finger when I stretch my hand towards her. I wonder what she's saying.
There are more than 20 muscles in each ear to help cats rotate their ears in many directions enabling them to easily find the source of a sound. A cat may be ignoring you, but their ears give them away. Feline hearing is five times greater than us humans.
The gene that results in the orange, tortoise-shell coat pattern of a calico cat is linked to the cat's gender, which is usually female, but occasionally it will be a male. My mother-in-law had a male calico. She named it Tootsie after the movie.
Cats step with both left legs then both right legs when they walk or run, and they always walk on their toes making them quiet hunters.
Never give chocolate, anything with onions in it like gravy, anything with garlic in it like hamburger to your cat. These things are poisonous to them.
What you can do is give them lots of love and feed them a healthy diet. Talk to your local veterinarian about what's best to feed your cat. Different cats may have different needs based on age or health problems, etc. Most of all enjoy your cat.
