How much money does it cost to have a pet?

I have a dog. She's a Lhasa Apso cross Papillon

Purchased in 2011 for £150
Food: around £3 a fortnight (she also eats a lot of leftovers that the kids leave)
Treats: around £1 a week
Grooming: £30 every 3 months

Sadly my poor dog has cancer which has spread to her liver. So far, since Bonfire night, her operation (full mammary strip - she had an enormous infected tumour), medication, and ongoing treatment has cost in the region of £2,500 so far.

We have a cat. She costs £10 per month for vets for pets which is a plan for things like worming tablets, yearly injections, regular flea treatments.
Wet food we spend about £5.00 per week
Box of go cat munchies is about £1.50
Cat litter (shes more a home cat than a going out cat, she goes to the back garden and thats her safe space) So we spend £6.00 every couple of weeks for the clumping one.
Then you need a claw scratcher post, litter tray, toys, food bowl. Also having her spade as well if you dont want kittens.

Wow that's a fair amount - is that mainly from food or other things? Are vet bills really expensive?

I am very fond of cats and dogs but currently have two dogs. Right from the start, my boys have cost a fortune in vet bills. I have the gold insurance type. I just love my dogs.

Most recent bill was for a badly swollen infected anal gland. Poor sausage. They filmed the evacuation proceedings on the veterinary nurse's phone and showed me. It was like Dr P Popper.

Purchase price of my dogs was 90 pounds each donation to the excellent rescue centre.

My colleague spent a lot on his pet mouse when it was ill. It was part of the family. I think it cost over 500 and maybe over 1000 but not sure.
