I do wonder sometimes, if the treatment vets give is necessary in all cases. I know quite often the treatment is definitely necessary ...but .....if we are told our cat or dog needs this or that, we nod and pay up, don't we?
Some time ago, one of the farm cats disappeared for two days, and when she returned she had the most enormous abscess on her face. Our vet was closed, so took her to the next nearest. Fortunately she was one of the quieter feral cats, and we could actually hold her still. Vet kept her in to drain the abscess, and cut away the bad bit. Fetched her home next day, with lampshade on her head (yes, she loved that ...not!) lots of tablets, etc. etc. She had to go back twice a week for about a month. I think the bill was about £400 altogether, and we are not insured for the cats. When we went back, the vet only looked, told us to carry on bathing it with hibiscrub and keep on with the tablets, and that advice was another £20 each time!!
Then, another of the cats came with a large swelling. My OH said there was no way we were forking out another £400 - and I could not get near it to catch it anyway!! This abcess grew as big as the other cats, but my friend who is into herbal remedies, told me not to worry, it would go down .....I did worry, but not alot I could do if I could not catch her to take her to the vets. Meanwhile she told me to give her crab abble in her feed. I did this for a few days, and was so relieved when the abscess started to shrink.
So that abscess cost me a fiver. Wish I had done the same previously!! I have treated another cat the same way, and she too recovered ok.
