I know rabbits don't have heat cycles, but is it possible for a 7 month rabbit to have a period? This evening at feeding time my new Satin had blood in her cage pan. Definitely blood, not just red urine. Was very concerned so checked for broken toes, bite wound, etc. Checked her anal area as I wormed all my adults with Safeguard earlier in the day. Nothing around anus, but vulva is very swollen, wet, and tinged with blood. All other rabbits have no signs and this doe is acting fine and eating. What's going on???
