From :help :bar you can see that :function is one of the Vim commands that cannot be separated by a | character to chain commands together.
Unfortunately, unlike most Vim commands, this does not work:
:execute "function Meow()" | echom "Meow" | endfunction
You need to use this workaround for one-liner functions:
exec "function Meow()\nechom \"Meow\"\nendfun"
You can also just type the function one line at a time; Vim goes into some special mode when you run the command ":function Meow()" by itself, which is ended when you enter the ":endfunction" command.
Note that the normal use of functions, is in a script file, where you use multiple lines.
