How can animals sense earthquakes before they occur?

I don’t think the evidence is yet conclusive that they can. Much of the anecdotal evidence is tainted by recall bias. For example (but not a real example) someone remembers birds stopped singing just prior to an earthquake but observations of the same birds after the quake show they all stop singing at the same time quite often, it’s just in this instance they did so immediately before an earthquake.
