My animal food cost's are:
$20 a month on crickets for 1000
$10 a month for rat chow because we breed rats to feed my lizards,frogs,turtles and snakes( rat pups cost $5 so it's cheaper to raise our own)
under $10 a month for rabbit food( a $16 bag lasts 3 months feeding 2 rabbits less in the summer months)
$10 a month for dog food
Under $1 for our cockateals as we have bought seed cheap a while back @.10 per 2 kg bag and we feed boss for a treat
our GP gets fed scrap fruits and veggies and rabbit pellets
$2 for the turtles a month for goldfish , they get pinkies and other creap treats.
$5 Savannah monitor as it eats shrimp,fish, bugs,worms,home grow pinkies, what ever's cheapest/healthy
$10 for cat food
Don't know about the chickens yet as I bough a tiny 3kg bag of feed for $2 but I think it's just scratch which is just a treat apparently so until I go back this weekend and buy layer food I'm giving lots of supplments like hemp seed.
So about $60 max a month on feed
