Eggs?

[akiso914]

I found these little white spheres stuck on the glass of my tank earlier today - are they eggs? My axolotl is alone in the tank - do they lay infertile eggs ever? Still not entirely sure of the gender, (she I think) is almost a year old.

Yes, those look like eggs. Some females will occasionally lay a small number of infertile eggs without a male present.
