There are several human foods you can use as emergency cat foods. Please note that all the listed options are meant to be temporary only and cannot provide a balanced diet long term.
Despite what comics and TV shows portrait, cats shouldn't be fed any milk or cream. They become lactose intolerant early in their life (soon after the mother cat stops feeding them milk) and after that time milk causes discomfort, bloating and diarrhea. Having diarrhea can severletyseverely dehydrate the body and lead to even more loss of essential nutrients.
Other options to temporarily feed the cat (according to this post and personal experience) include:
- Raw meat like chicken, lamb or fish (no raw pork)
- Unseasoned cooked meat or fish
- Cooked or raw eggs (only feed raw eggs if you're sure they don't have salmonella)
- Small quantities of plain yogurt that must not contain Xylitolxylitol
- Unseasoned cooked grains like rice, oats, couscous, polenta, millet and even breadcrumbs
- Unseasoned cooked potatoes or potato mash. You can use instant powder, but you must read the list of ingredients first and make sure it doesn't contain any onion or garlic at all.
- Small amounts of finely cut, microwaved, steamed or boiled carrots, peas, green beans, broccoli, asparagus, pumpkin, squash and spinach. Please be aware that there vegetables like onions, garlic, leek and avocados that are poisonous to cats. See the Pet Poison Helpline for more details.
Unseasoned broth is a good emergency food for all cats that are unable to eat solid food. The broth should be as thick as possible (use less water for the same amount of meat) and can be made from chicken or other poultypoultry, any bones, pig's or calf's feet, fish heads and fins or any cutoffs you can buy cheap. You should also try to cut some meat very small and add it to the broth. A small amount of instant potato mash, cooked potato mashed finely, flour or starch also adds more nutrients to the broth. (If you add flour or starch to the broth, dissolve it in a little cold water first and then add it to the boiling broth and cook for 2 minutes. That gives the broth a gravy or sauce-like consistency.)
