Very salty and fatty. A tiny treat occasionally, never regular — salt poisoning is possible in small dogs.
Short answer
A tiny piece of ham is okay as a very rare treat, but it's not good for them. Ham is very high in salt and fat, which can upset your cat's stomach or lead to salt poisoning over time. Watch for vomiting, diarrhea, or increased thirst. If you see any of these signs, call your vet.
