Could the Oils Present in Pine Litter Poison My Cat?
Most likely the answer to this question is no. Pellets manufactured for pine cat litter are kiln-dried, a process that bakes out potentially harmful oils, phenols and hydrocarbons. Any compounds missed by the drying process are captured and squeezed out by pressurization, pretty much eliminating the threat of toxic chemicals.
If you are unsure whether your brand of pine litter is manufactured by these same stringent methods, write to the company or call its customer service number and ask.
Unless your pet has some kind of severe allergy or underlying health issue, it should be able to use pine cat litter without becoming ill.
