Karenjet, I’m assuming that, like everyone, you are not able to have a face to face discussion with your vet and that everything so far is being done over the phone. While this is okay for anything that is straightforward, I think most pet owners would struggle with a lot of new, possibly complex, information relayed through a phone call. I agree with Lyn that you need more information.
I suggest that you email your vet and set out:
• the bits you do understand – eg Belle’s problem is not down to crystals
• the bits you don’t understand/are not clear about/need more explanation – eg exactly what tests have they done so far, do they know where the blockage is/what it is or is likely to be
• what are the options for removing the blockage
plus anything else that you can think of.
Ask them to reply to you by email because you need time to digest the information and you can’t do this with a phone call. (And remember, lots of people, with or without mental health issues, prefer written information they can refer back to!)
This should give you more, clearer information and help you decide what you want to do and whether or not you want a second opinion.
Belle is currently in safe hands in that his problem in peeing is being managed by the vets. Given that he appears otherwise fit and healthy, I don’t consider you are being cruel in wanting to explore all the options.
Please come back and let us know how you get on.
