Bacon has high fat and salt content which can lead to obesity, pancreatitis, and other health issues in cats.
Bacon grease can also cause an upset stomach.
Suggestions
Avoid giving bacon to your cat regularly.
If you decide to give a small amount, ensure it's cooked and all visible fat and grease are removed.
A sliver the size of your little fingernail is sufficient.
Opt for healthier meat options like cooked turkey or chicken breast.
Note: even if labeled as safe, any food can potentially cause allergies. When introducing a new food, please feed a small amount and observe your cat for any allergic reactions.
