I do realize spaying is best. I would do it if I had the money but right now that isn't possible. I do plan to take Jazzy to the vet for this lump. I will see what the vet can do for her. I will let you know the status of this situation. It isn't a question for me whether a rat is worth having spent a lot of money for medical care. I would do it in a heart beat, no questions asked..and I have. Like I said previously, I have spent more than $2,000 on my rats for medical care..and that is not included the times I paid to have them pts. I am not particularly worried about respiratory issues at this time. I wouldn't have been able to say that in the very early part of my having rats, because I wouldn't known exactly what to do for them. However, I have gained more knowledge about how to treat them. I have my own stock of medications. I have the basics...baytril, amoxy..doxcy..metacam, motrin, prednisone. I am comfortable with treating them for respiratory issues. However, when it comes to those d%#^^# lumps! forget it. Obviously I can't remove them. Wish I could. I had my boy Splinter operated on to remove that walnut sized tumor from the top of his neck. He healed nicely after the surgery..no abcessess but then 3 wks later he started with some respiratory issues. Before I knew it, he had died in his sleep. Now there is nothing to say that he would or wouldn't have died if I didn't have the surgery. It just had to be done period. I had a boy Stewart, whom I had to rush to the PET ER to have an emergency neuter. He ended up with a nasty abcess and I kept taking him back. He had such a nasty abases that he had 4 different bacterias in there. It cost me bookoo bucks to take him back and have needle aspirations and labs tests run for this infection. We had him on strong antibiotics for 30 days..He was getting worse and there wasn't anything I could do for him but to put him to sleep to relieve him. That's what I did. I had spent $360 for the neuter, and several hundred dollars afterward only to have him pts. Was it worth spending the money? Yes, most surely. I loved him very much. Some people would think I was a nut to spend that much money because in their eyes I could go get another rat for $8. That may be true, but not my rat..not the one I loved and that loved me. I do think it is worth it. However, times are tough and I'm trying my best to give my rats a good home. I know they are getting a better home than most are! I have considered sticking to boy rats, but I ended up having one girl left and that is why I took the new girl so she could have a friend. They both are real sweeties.
