I guess it depends if you just have
to buy stuff for them every single time you walk into a pet store!
no really, a rough guess.....
****dry food $10 for a small bag (I use good dry food, Nutro) that lasts over a month, I leave it out all day for them, oh & I have 2 cats
****wet food....I feed them each a small can of wet for brkfst & dinner, so it depends on the brand, I mix the nutro wet & the fancy feast elegant medleys that they love so much....but I want to get some nutrition in them, so I mix it together....I get the FF on sale for 59cents a can and buy cases of it for that cheap (it's usually 89 cents for 1 sm can) so that's $2.36 a day for 2 cats
****litter, it's not so much the brand, but how often you scoop. You can get the petsmart brand clumping exquisicat litter in a 40lb box on sale for $9.99, this will last me a month, or maybe 5 wks.....but I scoop their business everytime I take out the trash (almost everyday....maybe it'll go overnight), this cuts down on odor too!
****don't forget vet care....kitty will need vaccinations, unless you adopt, all vet costs are covered in the adoption fee....otherwise you have rabies shots, distemper & a booster for this one, and then the neuter/spay (very important).....
****and there is all the start up stuff, bowls=glass or stainless, don't use plastic! and a collar, and tag..... and don't forget a litter box....those will run you about $20, and I use litter liners! This way the litter box doesn't get so gross when you clean up, it makes changing litter a breeze! And you don't have to get so caught up on toys, a kitty will make a toy of anything!
