How to take care of your cats

Feed them with natural food not commercial dry powdered foods. Although natural foods involve more preparation it really doesn't with the right steps. You can prepare a lot of natural cat food and store it in the fridge or freezer. When storing it in freezer be sure to put it in separate containers. You can also mix a little bit of vinegar or wine if storing it in the fridge to last longer. Note that storing it longer will also decrease the nutrition, taste, texture, and aroma of the food. If the cats are not spoiled or native they'll still eat it anyway. Only mix probiotics and vitamins when you're ready to give the food. You can search on google of foods that aren't allowed to cats and foods that are appetizing to cats. I usually mix the food with allowed fruits and veggies. Not to add to much because they wont eat it. I also mix meat stock, rice, and some commercial cat food to save more money, and increase nutrition thereby preventing diseases to prevent veterinary expenses. When i can't give them anything I give them rice with soysauce mix with a little bit of malunggay. Cats have little kidneys so dont give soy sauce often which is high in sodium. It said on google that grinded pumpkin seeds can get rid of worm but I haven't tested. If youre planning to give it though be sure to test it first on one cat and very little amount then monitor for the cats behavioral changes. Same procedure when introducing other types of food. If effective maintain the diet so the worms will be completely eradicated, and maintain nutrition levels. Also clean the cage with Clorox to remove the egges on the surfaces so the worms wont come back on the cat. 

I dont give them a bath especially if they have companion cats in the cage because they clean each other. Otherwise if the cat was contaminated from outside environment I'd give it a bath and some probiotics to prevent to exposure to diseases to other cats. 

Depending upon the cats behavior if I want to let it free roam in the backyard. If the cat is careful doesn't go outside I'd let it roam around the house to prevent rodents. But the rodents also carry diseases, maybe it will turn them away seeing the presence of a cat. 

The advantages and disadvantages of keeping cats in cage is they are not exposed to contaminants except if the cat already a carrier of a disease this will infect other cats. The cage must also be properly cleaned regularly otherwise the feces and urine will harbor many bacteria causing diseases to cats especially if they are old or with a current disease they wont be able to resist it thereby becoming infected. It also needs to be under a tree or with an insultion ceiling to prevent too much heat. The cage also needs have very small holes so no passers will be sble to throw poisonous foods. Keeping them in separate cages also prevents them from multiplying and being exposed to outsider cats diseases. The cage need to tall and wide enough to accomodate space for the cats. Some cat like the solitary and they will compete for space. The cage also needs to be separated enought from the ground so the smell of the fell feces and urine wont reach the cats much, but they'll still smell it so you still have to clean. The water needs to be hang on the upper side of the cage where they won't reach it for urinating. If you leave the food bowl empty they would also urinate and defecate in it so take it once they are done eating. Food scraps will also fall off below the ground so be sure to put a blockade or clean it so roaming dogs wont reach it.
