Persnikety

Some one or some creature who is very, very picky about what they will eat, what they will do, what they will watch.

Gizmo is very persnikety about what she will eat and how it is arranged before her!

pursnickety

Excessively picky about finances; being a penny-pincher.

Ebeneezer Scrooge was so pursnickety that he would endanger his own health and safety ("Cold and darkness are free; I love them! Saves on coal and candle-wax!") just to avoid spending a few farthings.
