Get will return CatType, which is apparently a record containing the
fields ID, Age, Lives. So to compare these three values you need
something like: 

FOR I IN 1..5 LOOP

    if  Get (Cats(I)).ID = <user_id> then
        ...
    end if;

    if  Get (Cats(I)).Age = <user_age> then
        ...
    end if;

    ...
 END LOOP;
