For sure! I mean everyone know what happens when one gorges on too much fruit, right? haha!
That's why I don't give them the flesh of melons, just the rinds (after I eat the flesh).......
.....I have a stash of melon rinds (and other veggies scraps) in the freezer to dole out in mid to late...
A large shallow pan with some paver blocks and ice cubes in it,
set in front of that fan can offer some extra coolness too.
Note, feeding watermelon can make for some funky colored poops too.
Black poops can be from eating dirt or cecal poops.
