Poorly Spencer

Don’t think Spencer is very well at the minute

Symptoms:

• Lethargy
• Dry nose
• Slight loss of appetite
• Greasy coat
• Occasional shivers 
• Weak Hindquarters at times
• Weeing more than normal

If anyone has any ideas of what it could be that would be great, at the moment I’m either thinking low blood sugar or possibly a cold as I have had one recently. If he doesn't perk up by Monday I think I’ll take him to the vets.

UPDATE:He's perked up a lot in the past couple of hours, but that may just be because I've been giving him a lot of attention but at one point he either collapsed or laid down in his general play area part of his hutch which he has never done so I got really worried and made sure he could get up and move about.
He is also only a year old!
