BUMP! BUMP! BUMP!
Thank you for the update and I am so sorry that Conker is still having seizures! I do not know of any facility or Veterinarian in Ontario who will consent to evaluate, treat and return a Squirrel but others may know of such a facility or individual! My post will BUMP your question back in view of others once again! Hopefully someone will have some suggestions for you. IMHNVO (in my humble non-Vet opinion); Conker should be on some definitive anticonvulsant medication such as phenobarbital. There are others as well and I certainly hope that Conker can be seen by a Squirrel friendly and rodent experienced Veterinarian ASAP!
Regards,
