I would paint the cabinets in a soft white not a bright white or for color yellow. It would make it brighter. I would change the light fixture it looks like it could be flourescent. I would go vintage style on your appliances...kinda like the ones Rachel Ray has because your kitchen is very much a cottage kitchen. The floors you could do hardwoods, but with the in and out of the pets I would suggest a slate or an industrial grade linoleum tile. You can use 2 colors you can custom order these from Home Depot. I would not use a white tile...especially with pets...shows everything and will drive you crazy. I think a laminate countertop with a bull nose edge if you are on a tight budget. If you have favorite kitchen accessories you may want to consider these win choosing a color palette. Keep your knobs brushed nickel and your other fixtures as well. Send us a pic when you finish!
