Minecraft no animals?

I have nh ask me and my girlfriend in the world spaenen so many animals that just annoys when you run around our city all the time, now we have the question of whether you can exhibit that because with your friend he has no animals only cats in the world (he spawned them)

/ gamerule doMobspawning true

Thank you very much

Let me know if it helped ^^

We're going to try it out right now

Unfortunately it didn't work out for us, but we also play bedrock editon (pocket)

Yes, it should actually work there too

'/ gamerule doMobspawning false

and then to delete all animals: / kill @a

The other wrote true instead of False

Of course you can't. You wrote true instead of False
