It would be easier if your XML document used XML tagging for all its
structure, rather than using a comma-delimited syntax internally.

But if you must use this syntax, you can select the relevant elements using,
say:

<xsl:variable name="v" expr="normalize(animal/text())"/>
<xsl:if test="starts-with($v,'cat,') or contains($v,',cat,') or
ends-with($v,',cat')">

This assumes there are no embedded spaces.
