Identical neutral kaon pair correlations are measured in $\sqrt{s}=7$ TeV ppcollisions in the ALICE experiment. One-dimensional K$^0_s$K$^0_s$ correlationfunctions in terms of the invariant momentum difference of kaon pairs areformed in two multiplicity and two transverse momentum ranges. The femtoscopicparameters for the radius and correlation strength of the kaon source areextracted. The f${\rm i}$t includes quantum statistics and final-stateinteractions of the a$_0$/f$_0$ resonance. K$^0_s$K$^0_s$ correlations show anincrease in radius for increasing multiplicity and a slight decrease in radiusfor increasing transverse mass, $m_{\rm T}$, as seen in $\pi\pi$ correlationsin the pp system and in heavy-ion collisions. Transverse mass scaling isobserved between the K$^0_s$K$^0_s$ and $\pi\pi$ radii. Also, the f${\rm i}$rstobservation is made of the decay of the f$_2'$(1525) meson into theK$^0_s$K$^0_s$ channel in pp collisions.
