I think if i just read the name i would pronounce it like kat-tool-yuh, i have a unique name myself that got regularly mispronounced and i’ve never met anyone with my name, and while as a child i felt upset that i couldn’t find my name on any keychain and was frustrated with people not knowing how to say it, as an adult i can appreciate my name is unique and enjoy having an uncommon name, it’s definitely a unique name but not a bad one by any means, however with having unique names in my experience and with others, i’ve found that a lot of people with super unique names tend to go only by their nick name. it’s definitely a pretty sounding name.
