OYESauto Cat Water Fountain Filter and Pre-Filter Sponge Filter Out Fresh and Clean Water and Protect Cat Fountain Pump (8 Pack) - 8 Count

why does mine get my floor all wet around it?

I change the filter every 2 weeks and I wash the entire water fountain when I replace the filter. I found that the filter turned red this time around?

Why does the sponge smell after a week???, in filtered water. Cant get the odor out

Why does the black sponge smell, cant get rid of odor, dont sponges attract bacteria??
