My 67th English Gogyohka

^^
I have no corrections.

Some better words you could consider for "stepping" to also show that it was slow would be:

"my cat inching down"
"my cat creeping down"

Thank you !
I prefer "my cat creeping down"

You could also say 'descending the stairs'. Some more common English onomatopoeia for walking might be: tap, pat (since it is a cat's soft paw), or pitter-patter (which is often used to describe the sound of little children running around). But, of course, there are many options.... :)

There are some lists here: http://www.writtensound.com

Thank you, 深縹
I prefer "pat,pat, pat" beause its onomatipoeia is a bright and light sound and it is similar to the sound of French onomatopoeia "poc,poc,poc".
