I am the proud mother of a Snow Leopard Bengal who is 6 yrs old. We have been through the mill with him. When he was 2 he got a steroid shot for allergies. He went into congestive heart failure and almost died. He is very medication sensitive and a real dickens to treat. For the last 4 weeks we have been dealing with a chronic stuffy head. Sounds like he can't breath. He eat and drinks normally but he has so much head congestion. Thus far he has been on oral antibiotics, which made him vomit, nebulized twice which helped for about two days and two days ago he was given a long acting antibiotic injection. All seemed well until about an hour ago. Back to sneezing multiple time with snot flying every where. I was able to catch some and it looks clear with maybe just a tinge of yellow, very slight. The vet who is treating him is at wits end and so am I. She wants to sedate him and do a skull x-ray to investigate his sinus area. According to his cardioligst he should only be sedated if it is a matter of life or death. Can any one help? Please
