reminder: cats are predators.

The study found each feral cat kills an average 576 native birds, mammals and reptiles per year, while pet cats kill an average of 110 native animals every year – 40 reptiles, 38 birds and 32 mammals.

In Australia 3.7 million domestic cats kill 230 million native birds every year.

OP numbers are in the realm of not being plausible, unless the cat lives in a cage.

As a cat owner I could believe in 5 in a year, or one every 2-3 months, that's possible, low but possible. I can't honestly believe in 5 in 13 years, for a normal, non disabled cat.

Numbers I gave you are consistent with the 100 million cats that live in USA (15-30 birds killed by each cat every year on average)

The posters cat likely spends much more of its time on mammals as targets than on birds (the post does imply it takes a large harvest of vermin mammals).

Other cats may largely target birds.
