How many cats can a person legally own? When does someone legally have to many cats?

Call animal control. My idiot neighbor used to put milk out for strays and one day I counted 23 cats in her driveway. She was given 2 tickets for $1500 each, yes fifteen hundred dollars for not having them on leashes, no rabies shots and no county registration. This is after I caught 15 on night in my yard in a live animal trap. Mr. Kitty and I took a road trip and I dropped them off 10 miles from home. Apparently none of them had MapQuest since I have never seen them back again.
