I would never shave my precious 16 yr. old Ragdoll girl. She gets brushed and combed twice a day and loves the regular attention; and preens herself afterwards. She actually waits on her pillow every morning for the routine (after which she gets one or two natural treats). She has Stage 2 kidney disease currently, and I will keep her comfy with sub q fluids twice a week and extra water in her food as long as she has a good quality of life which includes keeping her in her natural state.
Kitties do not like to be naked, they get 'weirdly' ashamed. My neighbor insists on getting her Maine Coon a 'lion cut' every spring, and then wonders why he goes into hiding under the sofa during the day and only eats at night. D'oh !
Please people, enjoy the beauty of your kitties ... they are not going to be around forever.
