Tiger Town by Eric Walters

Eric Walters' series about the zoo next door continues!
Mr. McCurdy and Vladimir are well on their way to installing the new animals on Mr. McCurdy's farm: Boo Boo the bear, Peanuts the elephant, Kushna the tiger, and Sarah's pet deer are joining the family of exotic creatures, and it's hard work moving them in.
But when a young boy sneaks into the big cats' barn, mayhem breaks loose. McCurdy's old rival, the community's mayor, has an excuse to question the security of the exotic animal farm - and soon they're threatened by an overzealous inspector. The local newspaper gets in on the action, and animal-rights protesters invade the farm. To make matters worse, Sarah and Nicholas's mother is dating the police chief! Whose side will she take in the fight for Tiger Town?
