SAN DIEGO -- A feisty feline that lived in Escondido's city library and gained national notoriety for attacking dogs and sparking a $1.5 million lawsuit has died.

Known as L.C., for Library Cat, she suffered recently from seizures caused by tumors, according to The San Diego Union-Tribune.

City Librarian Laura Mitchell told the newspaper the cat died quietly at a private home in Escondido over the weekend. She was almost 11.

"I think she had a very good life," Mitchell told the Union-Tribune. "She had a lot of people who loved her, and she was really spoiled while she was here."

For much of her life, L.C. lived in the city library, where she apparently developed a distaste for dogs.

L.C. jumped into the national spotlight three years ago when the owner of an assistance dog sued the city after L.C. attacked the canine inside the library. The dog was not seriously hurt.

In the suit, Richard Espinosa contended that a sign that said "No Animals" except guide dogs violated his rights and those of others who use assistance dogs. Espinosa said he relied on the state-certified assistance dog to help him deal with anxiety attacks and other health problems.

Espinosa's suit charged that the city violated his civil rights and rights as a disabled person by "putting the welfare of their dangerous cat above people with disabilities."

The incident with L.C., he said "caused him to come into an unknown and very dangerous and unsafe situation striking terror in (him) and causing him lasting physical and emotional injury" and harm to the dog.

Espinosa rejected a $1,500 settlement offered by the city last year.

Deputy City Attorney Steve Nelson told the Union-Tribune the city plans to file a motion next month to dismiss the lawsuit.

L.C., adopted by the library as a kitten in 1994, became its mascot and unofficial greeter for eight years.

Because of her feisty reputation and run-in with the assistance dog and at least two other canines, she was forced into early retirement in May 2001 at the home of library employee.
