Addition, I do not know why but I have installed and used Optifine and now my cats are working. This is the only change made.
from Nyctophora re cats become non-responsive
I have this issue in Windows 7 using Minecraft 1.10 plain vanilla, Survival mode, no mods. I use Magic Launcher. I did not have this issue prior to 1.10. I have tried switching to Creative and spawning in all new ocelots which I then tamed. These new cats functioned normally for a couple of days (after switching back to Survival). They are now non-responsive again. They will show hearts if fed but will not breed even if close together.
I did not have this issue prior to switching my account from a Minecraft account to a Mojang account (not sure if this is relevant). The consensus on posts I have found is that somehow they are not recognised as 'mine' any more, but I can't re-tame them with more fish. The new batch becoming non-responsive is something I have not seen elsewhere. I hope you can help. Killing my kltties is a horrible solution! 😞
After a brief period with no more changes made by me the cats won't respond to commands again. I can briefly control new cats that I tame and then they too default to ignoring me as it were. Name tags do not appear to prevent this as one tagged cat stopped responding and now the other has too.
