%
%\subsection{Options}
%
%The basic cat can be modified by changing its colour:
%\begin{tcblisting}{title={Body colour}}
%\cat[body=blue]
%\end{tcblisting}
%
%In addition to the colour of the body, the colour of various body parts can be adjusted:
%\begin{tcblisting}{title={Eye colour}}
%\cat[eyes=green]
%\end{tcblisting}
%\begin{tcblisting}{title={Pupil colour}}
%\cat[pupils=red]
%\end{tcblisting}
%\begin{tcblisting}{title={Nose colour}}
%\cat[nose=red]
%\end{tcblisting}
%\begin{tcblisting}{title={Whiskers colour}}
%\cat[whiskers=red]
%\end{tcblisting}
%\begin{tcblisting}{title={Paw colour}}
%\cat[paws=red]
%\end{tcblisting}
%
% The cat can open its mouth:
%\begin{tcblisting}{title={Open mouth}}
%\cat[openmouth]
%\end{tcblisting}
%
%The shape of the \saminline|pupils| can be changed with the \saminline|pupilwidth| option:
%\begin{tcblisting}{title={Width of pupils}}
%\cat[pupilwidth=0.015]
%\end{tcblisting}
%
%Additionally several predefined widths exist:
%\begin{tcolorbox}[title={Predefined pupil widths}]

%There is also the special option \saminline|schroedinger|. This cat is both alive and dead as long as you did not compile your document.
%Be prepared for a possibly disturbing scene when you open the pdf, this option is not suited for sensitive \tikzlings.

%To view the cat from behind:
%\begin{tcblisting}{title={Back view}}
%\cat[back]

%The key \saminline|3D| will make the cat 3-dimensional:
%\begin{tcblisting}{title={3D view}}
%\cat[3D]
%\end{tcblisting}

%And finally the \saminline|contour| key will only draw the outlines:
%\begin{tcblisting}{title={Contours}}
%\cat[contour=black]
