All the kits will be longhair. If the molly carries dilute, each kit will have a 50/50 chance of being black/brown vs. grey. Otherwise, every kit will be black/brown. If both the molly and the tom carry solid, each kit will have a 25% chance of being solid vs. mackerel tabby. Otherwise, every kit will be a mackerel tabby.

Unless the tom carries chocolate or cinnamon, every kit will be blue-based. If the tom carries chocolate or cinnamon, each kit has a 50% chance of being blue vs. lilac (if the tom carries chocolate) or fawn (if the tom carries cinnamon).

The tabby possibilities don’t differ too much either way, honestly -- if the father’s a mackerel tabby, the likelihood of there being solid kits goes down, but that’s really the only effect. If either parent is a mackerel tabby that doesn’t carry solid, all the kits will be mackerel tabbies anyway. If the mother carries solid and the father is solid, each kit has a 50/50 chance of being solid vs. mackerel tabby. If the mother carries solid and the father is a mackerel tabby that also carries solid, each kit has a 25% chance of being solid and a 75% chance of being a mackerel tabby. 

Each kit will have a 50/50 chance of having less white like their father (anywhere from 0-60% possible) vs. more white like their mother (anywhere from 40-100% possible).

A grey mackerel tabby cannot be non-dilute, because grey is a dilute color. I’m going to treat this like an actual grey mackerel tabby, but if you mean something else (like a grey tabby with black stripes, for instance, which could be a couple of other non-dilute things), let me know.

Their kits will be non-red toms, red toms, non-red she-cats, and tortoiseshell she-cats. The red toms and red patches on the tortoiseshells will always be mackerel tabbies, whether they’re genetically solid or not. 

If the tom carries chocolate or cinnamon (unlikely, but impossible), each kit has a 50/50 chance of being chocolate/cinnamon vs. black (this obviously doesn’t affect the red toms). Otherwise, every non-red kit will be black (or black-based) in color. 

If the tom carries solid, each non-red kit will have a 50/50 chance of being solid. Otherwise, every kit will be a mackerel tabby. Remember that black > brown mackerel tabby in this instance!

If the she-cat carries dilute, each kit will have a 50/50 chance of being dilute (black > grey, chocolate > lilac, cinnamon > fawn, red/ginger > cream, tortie > blue-cream tortie, chocolate tortie > lilac-cream tortie, cinnamon tortie > fawn-cream tortie). Otherwise, all the kits will be non-dilute.

Each kit will have a 50/50 chance of being “less white” (one white-spotting gene) like their father vs. “more white” (two white-spotting genes) like their mother. Technically, “less white” spans anywhere from 0-60% white and “more white” is anywhere from 40-100% white. Realistically, their percentages are more likely to fall towards the middle of whichever range their genetics link to, but you can basically get away with a given kit having however much white you want (or don’t want) them to have.

Hope this helps!

All the kits (from either pairing) will be long-haired.

With the red tabby tom, the two of them will produce black/grey-based toms and tortoiseshell she-cats. If both parents carry solid, each kit will have a 25% chance of being solid. Otherwise, every kit will be a mackerel tabby (solid black turns into brown mackerel tabby, remember!). If the tom carries dilute, each kit will have a 50/50 chance of being dilute (grey tom, blue-cream tortie) vs. non-dilute (black/brown tabby tom, tortoiseshell). If he doesn’t carry dilute, every kit will be non-dilute. 

With the grey tabby tom, every kit will be grey. If both parents carry solid, each kit will have a 25% chance of being solid grey; otherwise, every kit will be a grey mackerel tabby. Each kit has a 50/50 chance of inheriting their father’s white-spotting vs. their mother’s no white spotting.

About half the kits will be grey and about half will be black. About half will be mackerel tabbies (remember, black > brown tabby!) and about half will be solid. If both parents carry longhair, about 25% of the kits will be longhaired; otherwise, they will all be shorthair. About half the kits will have some white but no more than 60%; probably somewhere around the same amount as their father.

We can’t accurately predict eye color (besides blue eyes, to some extent), so follow your instincts in regard to that.

Yes, that’s totally possible. The black she-cat needs to carry dilute, but that’s really the only thing necessary to make this possible. 

I’ll go ahead and answer this here since you added on the silver question.

To tell the difference between silver and grey, look at the stripes! If the stripes are black, the cat is genetically black and thus a silver tabby. If the stripes are grey, the cat is grey. Now, they can be silver and grey, and to tell if that’s so you look at how much contrast there is between the stripes and background. If the background is nearly white, chances are they’re silver grey.

If the tom is grey than the kit possibilities are:

Brown tabby toms, Ginger tabby toms, Brown tabby females, and Tortie tabby female. Half will have less than 50% white on them, a fourth more than 50% white, and the final fourth none at all.

If the tom is silver:

Silver tabby toms, Cameo tabby toms, Silver tabby females, and Silver tortie tabby female. Half will have less than 50% white on them, a fourth more than 50% white, and the final fourth none at all.

This is the same if the tom is Silver Grey. If the tom carries nonsilver, than possibilities from the grey cross are available.

I’m assuming you want kits lol?

brown tabby toms, ginger tabby toms, brown tabby she-cats, and torbie she-cats.

Half will have less than 50% white on them, and the other half more than 50% white (maybe even solids!)
