Suddenly my cursor in Ubuntu 14.04 LTS has become a cross mark in gnome-desktop. I've just installed oneko. Does this have something to do with the cursor?

I believe you have to move your theme to the /usr/share/icons directory for it to work.
Also you have to locate the index.theme (or any .theme file) of the theme you want to install and add it to update-alternatives using the --install option.
Let's take as example the theme ComixCursors-LH-White-Small ( a left-handed cursor theme from the package comixcursors-lefthanded ). Its
index.theme file looks like
[Icon Theme]
Name = Comix Cursor LH White Small Bold
Comment = The left-handed Comix Cursors - White Small Bold
Example = default
but it should have an Inherits line equal to the directory in /usr/share/icons in which the theme is saved, otherwise it won't work. So add
Inherits = ComixCursors-LH-White-Small
Now tell update-alternatives about your new theme
sudo update-alternatives --install /usr/share/icons/default/index.theme x-cursor-theme /usr/share/icons/ComixCursors-LH-White-Small/index.theme 91
where you should change the second last parameter to the index.theme of your theme. If you did this correctly
sudo update-alternatives --config x-cursor-theme
should display your new theme, and after logging out and in, your new theme should be applied.
Do System Settings > Displays
And turn-off / disable Unknown Display.

Install gnome-tweak-tool and then go to appearance tab and change the cursor theme to some other theme and back to the original one.
That solved my problem.
