The comic brilliantly plays with the physics concept of "strange matter" - a theoretical type of quark matter that could convert normal matter upon contact. Jon warns Garfield about strange matter, but our feline friend couldn't resist investigating... and promptly gets transformed into a swirly, quantum-warped version of himself! In reality, strange matter is hypothesized to contain strange quarks and could potentially be extremely dangerous - if it exists, touching it might turn you into more strange matter through a chain reaction. Thankfully, Garfield's quantum transformation is purely fictional, otherwise we'd have a cat-shaped strange matter apocalypse on our hands!
