Here are a few human foods that your cat should never eat.

#1: Raw Fish
Human-grade sushi is generally safe for people, but it can cause gastrointestinal upset in cats. ┬áThere is thiaminase in raw fish that could break down an essential B vitamin called thiamine in cats. Thiamine deficiency can cause neurological problems — and even lead to convulsions.
#2: Onions And Chives
Cats are considered two times more susceptible than dogs to the toxic allium components found in onions and chives, which can damage red blood cells even if a kitty only consumes a trace amount.
#3: Uncooked Eggs
Cats benefit from protein, but raw eggs may expose them to salmonella and other parasites that could lead to an inflamed pancreas, known as pancreatitis.
#4: Bones
Bones can splinter and cause a cat to choke, as well as block the intestinal tract, possibly even perforating the intestines. Never give a bone to a cat. And never give them anything that is as hard as their teeth, because it can cause dental fractures.
#5: Fat Trimmings
Feeding your feline fat trimmings could lead to gastrointestinal upset and even pancreatitis.
#6: Caffeinated Drinks
Some cats may be drawn to lapping up your coffee, tea or soda, but too much caffeine consumption can cause an increased heart rate and agitation in your kitty.
