bash cat multiple files

Question

I am trying to cat three files and obtain and insert a newline after each file ,I thought of using something like :

cat f1 f2 f3|tr "\EOF" "
"

without success.

What is the easiest way to achieve that ?

If you are not tight to cat tool only, use bat https://github.com/sharkdp/bat.

bat -p file1 file2 file3

also, if you have dynamic files count, one can use wildcard:

bat -p *.extension
