The boys - the three: £1000 pa insurance, circa £300 pa on flea drops, worm drops and vacs, £1500+ on food, £250 pa on emergency vet treatment - insurance excesses (sometimes more). £150 invested in a micro chip cat flap last year. £200 - £300 on the Cat Lady when we are away. Notwithstanding £60 on a new laptop charger for dd last week, because the lad the terrible chewed through it.
Three I think are a luxury but the first two came as brothers (and no, I don't think they are easily affordable) and the third arrived when neighbours moved (he had been "living" here for the previous 18 months).
The insurance I'm not sure about. One has been accident prone and has cost £3,500 in the last five years (amputated tail and life threatening poisoning - and off to the vet on Tuesday because he has a bleeding paw), the other bro has just developed diabetes, so I think it has paid for itself.
Having said that, they are our "boys" and we all love them and wouldn't part with them for the world. The wine, the beer, the mobiles, the cleaner, would all go first so they aren't really a luxury - more a lovesusry.
