Let's see ... for 2-3 piggies (I'm estimating and have had two or three piggies at different times, so I may have mixed values for 2 and 3 piggies).
I'd say lettuce and veggies, I can spend as little as $3 a week or as much as $15 for two weeks ... (well, I'm sure I could find ways to spend more than that, but you get the picture). That depends on 1) what's in season, 2) how much specialty lettuce and goodies I'm willing to spring for, 3) how much I have growing myself. Of course, we get some nice salads out of it, too ... the piggies "allow" us to share with them ... sort-of. So $5 a week is probably a good estimate for piggy purchases. That would about $20 for a month.
For hay ... it depends on the varieties I buy ... their primary hay, timothy, would be about $25 per month (though that could be reduced by buying the bigger boxes instead of the bags), but small bags I get for variety are more expensive, so probably more like $30-$35 for hay for spoiled piggies.
Their pellets are like $11 a bag which lasts a while, so I guess I'd throw a dollar or two in the monthly budgeting, but it's a minor cost.
When I used disposable litter, it cost me like $50 a month for the litter, and I'll say $4 for other (paper to line the cage, vinegar and paper towels for cleaning).
Now that I use washable, reusable bedding, it's pretty much just the extras and laundering, so like $6 for a month, but there was a starting cost on that ... $65 ish + existing supplies at home and the ability to sew.
If we buy bottled water for them, that's another $6-$7 a month because we can't deal with larger bottles.
Throw in a bit more for whatever the girls have begged out of me this month ... probably around $65 a month for a pair/small herd, but would be almost double with the skyrocketing prices of Carefresh if I hadn't swapped bedding.
1 USD = .79 GBP, 1 USD = .93 EUR ...
So I guess around £52 or €60, if conversion is valid?
