While we all love to spoil our pets, there are times that our fur-kids do not seem to get the same enjoyment out of a mass manufactured product as those that come from an individual crafter. The truth is different - this process is not as simple and painless as depicted by some, and the claws are not the only parts of the cat's body that are removed. If you just changed to a perfumed litter, or you just started using a strongly-scented cleaner, you may have found the problem.
