I was told to use a mixture of bleach and water to dilute the chemicals in the soil after urination. Also to try to get her to go in the same area every time.
Also not to let her lick us.
Good for you and Cosmo!
We've been told about the "HazMat" as well and will be stocking up on bleach as well as trying to get her to go in the same area for easy clean up.
Hope everything continues to go well.
Sounds like everything is going OK. Good luck with the chemo. I'll be watching out for updates from you and others going through it so I'll know what to look for with Cali.
