Cavatica

While there are many who would certainly be put off by the association with spiders, Cavatica has a spirited and spikey feel and sounds enough like Cassia, Catalina, and Callista that it leans "name-y". Cavatica appears in E.B White's popular novel, Charlotte's Web about a spider called Charlotte. A. Cavatica.

Pronounced kuh-VAT-i-kuh.
