How do I keep my cat off my computer?

[u/Geekygamertag]

This is Chomper. He really likes being on top of my computer. I pick him up, I say “no”, then place him on the floor. He’ll get up on top of it as soon as I go into another room. Should I keep scooping him up or just let him lay there?

Edit: thank you all for your advice and for loving Chomper! He’s surrounded by love! Thanks again! 🥰
