A TSH test measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland and tells the thyroid gland to make and release the hormones thyroxine (T4) and triiodothyronine (T3). Alternative Names.
The gestation period for a cat is 63-65 days. This varies between cat though, and anywhere between 60 to 70 days is normal.
The House Rabbit Society also says the gestation period for rabbits is 31 days, but I couldn't find sources (or conflicting claims) for the rest. By comparison, cats (left unchecked) have 2-3 litters a year with a gestation period of 58-65 days and a litter of 4-6 kittens (source).
