Maybe. Caustic soda is good on fats in kitchen sinks. For hairballs,
conc. sulphuric acid drain cleaners may work better.

Handy tip. I'll try that if I ever start suffering from furballs.

Caustic is much more effective when used boiling hot, but its not safe
stuff. One drop in an eye and youve really got problems, its worse than
acid.
