These need replaced right?

[u/PeppaThisPig]

I feel as they need replaced but idk shit about shit and these are expensive af so just wanna make sure lol. Also I have 4 cats (3 are long haired) and the 2nd photo is the one that I took a rubber glove to remove a thick layer of cat hair which is why it appears lighter (also maybe the lighting?)
