They did hurt some cats. You cannot do RNA sequencing without looking at tissue samples:

"We first performed RNA sequencing (RNA-seq) on skin tissues obtained from the auricles of different adult calico cats (#19, #20, and #22, females, precise ages unknown)"
Auricles are the earlobes.
"We then analyzed multiple skin tissues obtained from a young calico cat that died of unknown causes (#01, female, 3 weeks old) "
"A) Expression levels of ARHGAP36 and IGSF1 in cat auricles (left) and skin tissues (right). RNA-seq data were obtained in small auricle pieces of different coat colors derived from different cats (left) and in skin samples of different coat colors derived from a single calico cat (#01) (right)."

stray cats are fixed and have ears clipped in several countries so you have an excess of those tissues hanging around no matter what
First, it still hurts the cats.
Second, they clipped the cats ears at specific places because they needed different color hair follicle samples. They describe it in the paper.
