How many mice should I feed my mouser ?

[Eric Alan]

I'm not wondering about gram weight of her meals, I'm wondering how many prey items I can safely give her without her regurging.

You're asking two different things.

"How many prey items:"

• 179 / 40 = 4.475 (4x 40g mice)
• 179 / 25 = 7.16 (7x 25g mice)
• 90 / 40 = 2.25 (2x 40g mice)
• 90 / 25 = 3.6 (3x 25g mice)
• Average = 4.1 (4x 25-40g mice)

"...I can safely give her without her regurging.":

• Is largely dependent on the specific animal and other external factors.

You didn't say anything about regurgitation in your first post. That's why I gave you the advice that I did.
