Food and Water Bowls
It's best to give kitty the food she/he is used to. I like using Hill's Science kitty food. I also buy Fancy Felines food. If you want to switch and use a different kind that is fine but I suggest you do so slowly.
Long haired Persians should be groomed frequently to avoid matting. They should be combed at least once a week. I like using a steel comb instead of a brush. You can use a little cornstarch and rub into thier coats to help prevent matting and keep thier coats fluffy. If your kitty gets a "mat" gently work it out with your fingers or a comb. If it is too severe you may have to carefully cut some of it out to get it detangled.
I have yet to find a cat that enjoys bathtime! The best way I have found is to get a 2 tubs or sinks full of warm water. In one tub put a cup of apple cider vinigar or regular vinigar. Wrap kitty in a towel and slowly lower in the tub without the vinigar leaving it's head out. Let kitty soak for a few minutes and hopefully by then they will be a little more willing for it's bath. I like to use unscented shampoo for babies or something mild. You can also use dawn dish soap. You can start by cleaning kitty's face with a rag. Soap the rest of kitty and rinse in the sink with vinigar to remove all residue soap. Dry with a towel and finish with a hair dryer on low setting.
Some kittens have eye drainage due to thier fatter faces. Although some of my cats with flat faces have very little eye drainage. If you do have a kitten with eye drainage you will want to wipe the kitties eyes daily with a warm paper towel. You can purchase a product called "eye envy" to help with the staining.
