This is all food, I found from so many websites , and from some suggestions from all friends in CBD. To help your cat eat while they are sick and they hardly to eat anything. It's Additional Nourishment. But it's not something your pawrents should feed us cats in the long terms but which also can help keep them going at times of crisis, or enable them to eat.
Eggs
If you are looking to provide your cat with additional nourishment, one possible food might be eggs. "Proteins with high biologic value can be readily converted to body proteins with minimal waste production. Animal proteins have a higher biologic value than vegetable proteins. Eggs have the highest biologic value."
You can try scrambling the eggs, some cats enjoy these. Some people choose to only feed the white, because this provides additional protein but does not contain high levels of phosphorus. One large egg white weighs about 33g and contains 17 calories, 3.6g protein, no fat and 5mg of phosphorus. This is a lot less phosphorus than a chicken breast, and the protein in eggs is more digestible.
However, it is important to cook egg whites until they are hard, because uncooked egg white contains something called avidin, which combines with one of the B-complex vitamins (biotin) to make it unavailable. Cooking the egg whites destroys the avidin. Some cats will eat cooked egg white voluntarily, but it tastes a little bland that way, so most people simply mix it into their cat's other food.
In the USA you can buy cartons of egg white in supermarkets, but be careful because some brands contain onion ( No Good for cat ).
It is estimated that around 80% of cats are lactose intolerant, which can cause diarrhoea and vomiting. For this reason, it's usually recommended that cats are not fed milk, but if your cat is not lactose intolerant, it is usually safe to feed milk, though it does contain protein and phosphorus.
If your cat is lactose intolerant, there are special lactose-free milks available for cats.
Human Baby Foods

Baby foods can be helpful if you are trying to tempt your cat to eat in the short-term. Aim to buy the simple meat-based foods rather than those containing veggies and fruit. Please also ensure you purchase a food without any onion or garlic or onion powder
Do not feed baby foods exclusively long-term, because like other human foods they lack taurine, an amino acid which cats need to obtain from their food: a lack of taurine in a cat's diet can cause serious heart and eye problems.
If you feed them exclusively for longer than a few days, add 500mg of taurine to it, which is not perfect which will reduce the risks somewhat. However, it is OK to feed a little baby food each day without taurine e.g. when giving pills, as long as it is in addition to a more balanced (usually a commercial) cat food.
Human Food
This is certainly not the best food for a cat, but if your cat is recovering from a crisis or being extremely pernickety, you may have to resort to offering tasty human foods to tempt your cat back into eating.

Chicken or lightly cooked fish are possibilities. Thomas would only eat ham for two weeks when his anaemia was at its worst; even though the levels of sodium in the ham were very unhealthy, eating ham was better than not eating anything at all. Many commercially sold chickens have a lot of salt too.
Do not feed these sorts of foods long-term, because they lack the nutrients which a cat needs, particularly
taurine, an amino acid which cats cannot manufacture themselves, and a lack of which can cause heart and eye problems; but in order to kick-start eating, they can be ideal.
Please do not feed your cat anything containing onion or garlic and be careful about feeding tuna.
Tuna Water
Whilst tuna itself is not appropriate for cats, one possible compromise is to add the water in which tuna is packed to your cat's prescription or other diet in order to moisten it and make it more palatable. Tuna packed in water may actually be packed in a type of broth, which may contain onion; and other brands may contain high levels of sodium, so you need to be very sure the brand you use is acceptable.
PS : Any Suggestion or Your mom have more addition, Please fell free to make a comment because one of your suggestion can help so many of us to eat . And get back to be normal again.
