Hi there,Thanks for your question regarding your girl who has developed a soft lump. I am currently typing up a response and will have something for you in the next 5 - 10 minutes.Thank you for your patience.Kind Regards,Dr E
Hi again,Thank you for your patience. While there are a few things that could have caused this swelling including an allergic reaction (to a drug or bee/bug bite or sting) or a lymph drainage issue, if this has occurred within a few hours of giving the sub cutaneous fluids, then this is very likely the fluid running down with gravity to the sub cutaneous tissue around the leg. If you give the fluid under the skin behind the neck (between the shoulder blades) and the swelling is around one of the front legs, then this is very likely what has happened here.
Keep a close eye on your girl for the next couple of hours if you can. If this is just the fluid you gave, then you will find that it dissipates and the swelling settles in the next couple of hours. If the swelling becomes any worse tonight, then definitely do get her seen by your local ER vet as there is likely something else going on here. Hopefully she is otherwise ok (other than the vomiting you mentioned which isn't abnormal for a 20 year old cat with renal disease). Best of luck with your girl and hopefully this is just a once off after the sub cutaneous fluid. I hope all of the above makes sense?
