No, cats can’t eat mustard.
Mustard contains mustard seeds that can cause your pet cat severe gastroenteritis.
Cats will typically show at the very least a decrease of appetite, and possibly vomiting or diarrhea.
In addition to mustard seeds being toxic to cats, some may be allergic to them as well.
In all, it’s best not to feed your cat mustard.
What is gastroenteritis in cats?
Gastroenteritis in cats is the inflammation of the lining of their stomach and intestines.
This can be caused by eating something they shouldn’t, or more commonly it’s contagious bacteria you can catch from another cat.
Some common symptoms are vomiting, diarrhea, loss of appetite, lethargy, fever, and dehydration.
Can mustard kill cats?
Although it’s unlikely to kill your cat, it will make them sick for a while so it is worth taking them to the vet if you suspect they have gastroenteritis.
What should I feed my cat instead?
As always, make sure your cat is eating high-quality formulated food.
You can also try feeding them canned food or fresh meats like fish and chicken to supplement their diet.
If you want something similar to mustard for your pet cat, try giving her mayonnaise, as mayo is a lot safer than mustard for cats.
