Crackling under skin

[Candice Cottle]

My cat has feline diabetes. I test her twice a day and give her Lantus insulin. She has kidney disease and gets Sub Q fluids every 3 days. She has a weird crackling sound under her skin and it feels like there is something like plastic under her skin in the area of her shoulders and shoulder blades.
Has anyone experienced this
Thanks

I found this older thread regarding crackling under the skin - I don't have any personal experience, but you can have a look at the thread until someone with more experience comes along and maybe has a suggestion.

Crackling Noise Under the Skin (Subcutaneous Crepitus)

Occasionally you may hear a "crackling" noise under your cat's skin after giving sub-Qs and/or the cat may seem "squishy". This simply means that a little air has got under the skin (this is known as subcutaneous crepitus), and should go away on its own in a couple of days.

It is not usually anything to worry about unless it happens regularly. If it does, I would recommend that you discuss it with your vet because it may mean that your cat is overhydrated, in which case you need to reduce the amount of fluid which you are giving; or you may need to refine your technique so as to allow less air under the skin.
