Per year? Hm, more of an estimate since I grow some of my own stuff.
1. Around $130 (Oxbow 3lb bags x 8, each lasts about a month and a half)
2. Around $20-30 but depends on were I buy it and how much hay I harvested from my property.
3. It really depends on what I process for wood myself, money I have to spend, and if I can stock pile toy parts (a big order can last me years). So maybe an average of $10, but can be up to $100 or more if I have money to buy stuff online and/or I do a big order for parts.
4. $0 (I grow my own)
5. $30 (oxbow poof)
6. Not applicable, personally I don't do yearly exams, but I have a credit card for emergency vet use if needed.
7. Depends on the year and what is needed, if you're considering things like vinegar for cleaner, shavings for the litter pan, and stuff like that, maybe $10-20 a year.
Total: let say around $200 a year.
