I am wondering whether I can get rxparse to give score the text "cat"
within a variable but not other instances of cat contained in that
variable.

AN_IDrx = "`[$#  'cat'  #1]";
rx = rxparse(AB_IDrx);
call rxsubstr(rx, ANIMAL, start, len, Is_animal);
end;

(desired result) is that  is_animal = 1 for the second case ONLY.  I
have many other types of variables that have the same issue and I want
to score of 1 to happen only for the specific substring.

data like so:
ANIMAL
cat house
cat
cats
cat litter
cleaning: cat

Perhaps I am missing something but why don't you forget about using
PRX and just test for upcase(ANIMAL)=3D"CAT"?

Because that is much too simplistic for what I am doing.  I do have
substring within my data, but want to look for a specific instance in
one case only.

Can you provide some more examples? The rules don't seem clear to me,
I'd agree with Roland so far, just use upcase(Animal)=3D"CAT".

What about using the indexw() function in SAS?

Did you try using "cat " and/or " cat" instead of "cat"?  using both
should pick up instances in the beginning or end of a text stream....
