Squeak the cat was living life on the streets and spending time under cars where oil and other grime mixed with her fur to create thick mats along her back. This video shows how to use cuticle scissors to gentle cut out the mats. Fortunately Squeak is a very tolerant cat and did not mind having this done. This is best done as a two person job. One person holds and pets the cats while the other person cuts out the mats. Also Dawn dish soap is great for getting oil out of fur. That is what wild life rescuers use on animals affected by oil spills.
