I don't know if this is life threatening or not, but it has me worried enough that I can't sleep. Long story short, my 6-7 week old squirrel is seriously constipated. He tries and tries to poop, but its really hard for him. Sometimes his poop is so hard that I have to help him with q-tips and warm water, which he actually holds still for, something that he never does. This has only been going on for a day, and I thought he was getting better when he pooped a bit, albeit it was a bit hard for him, But I took a look at him again and noticed that the area upwards of his bum is round and hard to the touch. He is really full of poop, and it is very hard. Is there anything I can give him, not to soften the poop that's coming, but to soften the poop that's already there?

You'll have to excuse my ignorance, but I just found him and his brother a few days ago, and I've never rescued baby squirrels before...
