Is it safe for cats to eat butter?
Yes, its perfectly safe and normal for your cat to eat butter (if your cat don’t have milk allergy). My cats love butter and if I leave it only for a second on the table they will eat it without a trace.
I often add small pieces of butter to their food.
Most cats like to eat all kind of diary products and butter is actually good for them. Butter is one type of the human food that cat can eat without health issues caused by it.
