Does your vet refer to another hospital or can you text them? He might need gabapentin,  that is a hugely helpful medication for new amputees.  Again... I'm not a vet. Buprenorphine is a great medication but i don't know if the dosage may need to be tweaked a bit. 

Keep the fluids and any good wet stinky food or treats.  Huck latched on to the Delectables, which is mostly water but it did the trick. 

Tuna juice, low sodium bouillon are also good.  We like the taste of regular broth/ bouillon but cats can be turned off by the sodium content.  You can also simmer boneless chicken and make your own broth.  Just don't add salt.  They like the chicken too after it's been simmered so you can break it up and offer that too.

Do you know how to take a temp? That would be really helpful. You're at a point that can be tricky to tell what's going on.  101 to 102.8-103 is acceptable.  103 and higher is running a fever.  Some cats run high and 103 is ok but more than that needs to be seen.  

Stay calm and watchful.  Check out your alternatives and please keep in touch,  ok?

How are things this morning? Many of us used both the gabapentin and buprenorphine together, at different times. In other words buprenorphine on one schedule, gabapentin alternately in separate intervals. The 2 medications do different things and compliment each other very well. They are more effective rather than using just one or the other.

Can you feel his bladder? If he is laying on his side you can take your fingers and gently take hold of his abdomen right about where his legs meet his body. Squeeze gently and pull your fingers down until you feel what should feel like a ball of jello. 

Find and squeeze a cat's bladder

I found this really quick, it gives a good general idea. Now with that said, I could not just ever hold my Gazoo like that. He was a male cat that had FLUTD and he blocked frequently until he had surgery. I simply layed him on my counter which was a good height for me too, and I expressed him in the sink. Of course I bleached the sink after but you know what I mean. If you have pee pads you could lay him on the floor and do it over pee pads. It will be messier, but can get the job done. I suppose you could do it in the bath tub also.

24 hours is a long time for cats to go without urination. If he is eating and drinking he should be producing urine. Are you certain he has not urinated some place that you are unaware of? 

See if you can feel his bladder and let us know please. I totally understand what you are going through. Huck was a feral kitty that got injured and we also paid a lot of money. We had other furbabies with issues, I totally get it. I just don't want to see you get in to a situation of emergency and have something bad happen. 

Please let us know how you make out, ok?

Well, I am relieved to hear that his bladder is not too full!! I am so sorry you are going through all of this. Every vet does what they do differently. If he has some underlying issues they may not want to use both medications together. Where are you located at?

The gabapentin tends to make them drowsy at first, but after several doses Huck got more used to it and acted like his normal self. Groggy really isn't the worst thing in the world right now. They honestly need sleep to heal, and they need to take it easy for a couple of weeks. Fingers crossed that they did not find any crystals in his urine. 

Please hang in there, you are doing a great job! I know this is stressful and scary. There will be a light at the end of the tunnel, this is probably the toughest part of recovery. And as you can see, everybody recovers differently. 

Keep in touch, ok? If we can help in any way, we will. Even if you just need a sounding board to help get through it. 

Hugs,

Jackie and Huck  

Good deal. Im glad you got him in! Try to rest while U can.  Sending all the pawsitive vibes I can your way❤
