I really don't keep track of what I feed the dog. I feed her raw, so I buy her meat in with mine and well...
I think it's about $30/month MAX and approx $15/month MIN, but I have no idea what the true-to-life average is since we catch sales, or stock up for a while, or whatever. I know I haven't bought anything but a $1.50 package of hearts/gizzards this whole month since we had the freezer well-stocked. Freezer's nearly empty now though so next month should be a doozy.
I know a bag of feed lasts my chickens about 2 months, plus I get them some BOSS and suet blocks. I dunno probably costs less than $15/month all treats included.
My cat food had been costing about $12/month, but they discontinued my brand so I am not sure what the new cost will be yet.
My new coop costs so far have been:
$12 for two water buckets for new nipple waterers
$18 for water nipples & shipping
$10ish for nails/screws
$7ish for brackets for the 2x4's and gromet nails for the tin roof
$12ish for Quickcrete
$2 for blue plastic barrel for rain collecting
= $61 so far
Still need to buy a roll of hardware cloth and an 8ft piece of gutter to collect the rain and some hardware for the barrel (spigot, garden hose, etc) plus I'll have to fill it up with shavings/pellets when the time comes. I have gotten most of the materials by bartering with junk collecting or scrap yard owning friends
