Re^3: Checking a hash for two matching values.

It's easy enough to add case insensitivity to NetWallah's code with fc or lc.

For v5.16 or newer:

use v5.16;
...
my @found= grep { my %r =  reverse map fc, %$_;
                  exists $r{cat} && exists $r{dog} } @pets;

For older versions as well:

my @found= grep { my %r =  reverse map lc, %$_;
                  exists $r{cat} && exists $r{dog} } @pets;
