TRUE

Answer 1

In Prolog, an n-ary predicate p, for n≥0, is defined by a procedure, which consists of one or more clauses whose conclusions are terms of the form p(a1, ..., an), where each a_i is an argument. Clauses belonging to the same procedure are expected to be declared in sequence, contiguously.
When the clauses of two or more distinct procedures appear interleaved in the source code, the compiler produces the warning messages you get. To suppress such messages, you can use a directive of the form :- discontiguous predicate/arity.
For example:
:- discontiguous dog/1.
:- discontiguous cat/1.
dog(rottweiler).
cat(sphynx).
dog(poodle).
dog(bulldog).
cat(bengal).
dog(dobermann).
cat(himalayan).
cat(singapura).
Note, however, that the best option is to follow the Prolog convention and modify your code as follows:
% clauses of the first procedure
dog(rottweiler).
dog(poodle).
dog(bulldog).
dog(dobermann).
% clauses of the second procedure
cat(sphynx).
cat(bengal).
cat(himalayan).
cat(singapura).
